Background
There is currently an ever-increasing demand for pharmaceutical personnel in Tanzania.
This is due to expanding investment in public and private pharmaceutical sector. Shortage of
trained pharmaceutical human resource contributes to poor quality of pharmaceutical
services and low access to medicines in the country (GIZ, 2012).
Through Public-Private-Partnership (PPP) the Pharmacy Council (PC) together with
Development Partners (DPs) in Germany and Pharmaceutical Training Institutions (PTIs)
worked together to address the shortage of human resource for pharmacy by designing a
project named “Supporting Training Institutions for Improved Pharmaceutical Services in
Tanzania‖ in order to improve quality and capacity of PTIs in training.
CSSC prepared a Multi-actor Partnership (MAP) project proposal on how to sustain and
strengthen health care in Tanzania through improvement of pharmaceutical training and an
inter-institutional coordination of actors. This will harmonize and improve access to quality
pharmaceutical service in Tanzania.
The project has a various key stakeholders like; CSSC, NACTE, PC, TCU, CEDHA and
Pharmaceutical Training Institutions (PTIs). Through this project, few PTIs will receive
infrastructural improvements to increase the quantitative and qualitative capacities (CUHAS,
RUCU and KSP). Furthermore this project will train Pharmaceutical tutors from different
PTIs on teaching and assessment methods in Tanzania and thus improved health delivery
through increased qualified human resource.
It was also observed that in the previous stakeholder‘s meetings there was a need for the
development of training manuals and assessment plans for NTA Level 5 & 6, in order to
support the establishment and implementation of the curriculum in PTIs. During MAP kick-
off workshop done in February 2018, Stakeholders agreed that there was a need for
development of the said manuals and it was among the highest priority in Pharmacy
education in Tanzania. Therefore this project aims at developing facilitator‘s guide and
assessment plans for NTA Level 5 & 6.
Pharmacy Council, CSSC and action medeor developed the Terms of Reference and selected
a qualified service provider with experience in material development to develop the
mentioned training manuals and assessment plan. Centre for Educational Development in
Health Arusha (CEDHA) was selected and offered a contract to develop Facilitators guide for
NTA level 5 & 6 and assessment plan.
Centre for Educational Development in Health Arusha (CEDHA) was offered a leading role
with the instructions to include experts who have developed teaching materials for NTA
Level 4. These experts are primarily experienced pharmaceutical and non-pharmaceutical
tutors.
The mode of operation used by CEDHA to develop facilitator‘s guide and assessment plan
was participatory approach which included a number of activities through various workshops
such as planning, and orientation of material development. After these preliminary
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide iv
workshops, experts developed materials individually and in-groups. Thereafter, developed
draft materials were reviewed, edited and formatted and draft one was finalized and shared to
stakeholders for inputs.
Finally, CEDHA submitted the finalized Facilitator‘s guides and assessment plans for NTA
level 5 and 6 to CSSC for endorsement, printing, dissemination and sharing with relevant
authorities.
There are 12 modules for NTA level 6 making 12 Facilitator guides and one Practicum guide.

Acknowledgment
The development of standardized training materials of a competence-based curriculum for
pharmaceutical sciences has been accomplished through involvement of different
stakeholders.
Special thanks go to the Pharmacy Council for spearheading the harmonization of training
materials in the pharmacy after noticing that training institutions in Tanzania were using
different curricula and train their students differently.
I would also like to extend my gratitude to Christian Social Service Commission (CSSC) for
their tireless efforts to mobilize funds from development partners (German Ministry of Industry
and action medeor). It is through the implementation of the Multi-Actors Partnership (MAP)
project, CSSC has been able to provide the financial and technical support needed during the
development of this training material.
Many thanks go to the Centre for Educational Development in Health Arusha (CEDHA)
experts on health material development and training who coordinated the development of
these module sessions particularly Ms. Diana H. Gamuya for her commitment in coordinating
and facilitating the planning and development to its completion.
Particular acknowledgements are sent to Mr. Dickson Mtalitinya and Members from the
secretariat of National Council for Technical Education (NACTE) for facilitating and
providing their expertise to the success of this work.
It will be unfair if I will not recognize the efforts and contributions of all CEDHA supportive
staff that made this process a success; accountant, secretary, drivers and printers
Finally, I very much appreciate the contributions of the tutors and content experts
representing PTIs, hospitals, and other health training institutions. Their participation in
meetings and workshops, and their input in the development of this training
manual/facilitators guide have been invaluable.
These participants are listed with our gratitude below:

medical problems.
Other terms:
o First ―statistics‖ as a ―noun‖ means a descriptive measure computed from data of a
sample i.e. numerical statement – information that is available in numbers). Examples
of this include:
Hospital data on the number of admissions for some condition in a period
hospitals, health centers and dispensaries
This first part of the subject is usually referred to as descriptive statistics
o Secondly ―statistics‖ as a ―discipline‖ is a field of study concerned with:
Collecting, organizing and summarizing and analysis of data in a systematic way.
Drawing of inferences about a population on the basis of only a part of the
population targeted.
This second part, which, provides objective means of drawing conclusions,
constitutes inferential statistics
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 2
o A collection of entities.
o A statistical population means the largest collection of entities in which we have an
interest.
o Example we may be interested in looking at how may health facilities are given
Amoxil in district X?
o Part of a population.
o Example number of health centers given Amoxil capsules.
o Measures of central tendency provide a summary measure that attempts to describe
data with a single value that represents the middle or center of its distribution.
o There are three main measures of central tendency:
the mean,
median and
mode
Mean, arithmetic mean (X or M):
It is the most commonly used measure of central tendency.

individual scores vary in standard unit lengths from its midpoint of 0. For all normal
distributions, 95% of the area is within 1.96 standard deviations of the mean.
value. It is a mathematical expectation of the average squared deviations from the mean.
STEP 3: Importance of Measures in Statistics (45 minutes)
Activity: Buzzing (5 minutes)
ASK students to pair up and buzz on the following questions for 2 minutes
ALLOW few pairs to respond and let other pairs to add on points not mentioned
WRITE their responses on the flipchart or board
CLARIFY and SUMMARIZE by using the content below
o Measures of central tendency (Mean, Median, and Mode) in statistics
are important because of the following reasons:
To find representative value: Measures of central tendency or averages; give us
one value for the distribution and this value represents the entire distribution
Central tendency is very useful in psychology. It helps to know what is normal or
'average' for a set of data. It also condenses the data set down to one representative
value, which is useful when working with large amounts of data
The mean is an important measure because it incorporates the score from every
subject in the research study
o Measures of dispersion (Range of the Data, Variance, Standard Deviation and
Quartiles) in statistics are important because of the following reasons:
Variation is a measure of statistical dispersion
Quartile divides a range of data or population into four equal parts

STEP 4: Application of Statistics in Data Analysis (30Minutes)
of data.
o To assess risk in the pharmaceutical industries.
o To study biological phenomena and observations by means of statistical analysis
o To develop new insights and understanding of performance
o Serves as the foundation and logic of interventions made in the interest of public
health and preventive medicine.
o In clinical trials to arrive at optimal or near optimal solutions to complex problems
To quantify drug use
Statistics is an important tool in pharmacological research that is used to
summarize (descriptive statistics) experimental data in terms of central tendency
(mean or median) and variance
o It enables us to conduct hypothesis testing (to determine whether the pharmacological
effect of one drug is superior to another)
o Very helpful in formulating experimental design and drawing appropriate inferences
from the collected data

o They must be in aggregates
o They must be affected to a marked extent by a multiplicity of
causes.
o They must be enumerated or estimated according to a reasonable standard of accuracy
o They must have been collected in a systematic manner for a predetermined purpose.
o They must be placed in relation to each other. That is, they
must be comparable

PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 8
STEP 4: Sources of Data (25 minutes)
o Vital events register
This includes data on live-births, deaths, marriages and migration. This
register should ideally provide a comprehensive coverage of the whole
district/country. It is usually used to calculate demographic indicators such as infant
and under-five mortality rate
o National Population Census
This is an important source of demographic, social and economic data. These data
form the denominator in the calculation of many quantifiable health indicators.
National population census provides total population and age structure, which is not
easy to obtain through any other method.
o Routine data collection from health facilities
Routine data collection from health facilities is a good source of information for
disease, specifically morbidity and mortality data. This is because the information
is obtained from active cases and the data are collected by a professional, qualified
person.
o Sentinel surveillance
This is a system in which data is collected routinely from selected health facilities
or communities. It is very useful in obtaining specific morbidity data in a more
detailed form, particularly endemic diseases and those under special control
programmes, with an improved accuracy compared with routine data collection
system
o Surveys
A survey is very useful for evaluation because it can be done in a shorter time and
obtains a lot of detailed representative data. Surveys have the advantage of providing
timely and relevant information. Often surveys are done in the community, and hence
become more representative of the real situation than data obtained from health
facilities e.g. Demographic and health survey
o Reports and documents
A lot of reports and documents with useful information are produced daily in the
ministries of health, in training and research institutions.
o Scientific research
Research findings are usually of very high quality and can be useful in medium and
long term planning of health services. Comparatively, researches are more focused on
the subject matter than other sources of information
o External sources
o Data are collected by individual research workers or by other organizations through
sample surveys or experiments, keeping in view the objectives of the study in your
environment

pharmaceutical services?
ALLOW few pairs to respond and let other pairs to add on points not mentioned
WRITE their response on the flip chart/board
CLARIFY and SUMMARIZE by using the content below
o Primary Data
Primary data means the raw data (data without fabrication or not tailored data)
which has just been collected from the source and has not gone any kind of
statistical treatment like sorting and tabulation
Primary data is collected firsthand by a researcher (organization, person,
authority, agency or party etc.) through experiments, surveys, questionnaires,
focus groups, conducting interviews and taking (required) measurements
o Secondary Data
public through publications, journals and newspapers
STEP 6: The Quality of Data (30 minutes)
Data quality refers to the condition of a set of values of qualitative or quantitative variables.
making and planning.
o Timeliness: For data to become useful for decision-making it must reach the manager
at the appropriate time. Data on drug stock-outs and overstock should reach the
management before the meeting to make decisions on the type and amount of drugs to
procure for the next month.
o Accuracy: Data collected should be accurate enough for the manager to have
confidence in using it. However, despite the need for a high level of accuracy, it
should be borne in mind that any effort to increase the level of accuracy will be met
with an increase in the cost of collecting and processing that data. However, the level
of accuracy required in the day-to-day decision-making and planning is not as
stringent as may be required in scientific research.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 10
o Appropriateness: Data collected should be appropriate for the intended objectives.
Inappropriate data will not be used and may become an unnecessary extra burden for
health workers. Whereas the higher level requires strategic information to make
policy decisions, the lower level requires technical information to make management
decisions.
o User-friendliness: Data should therefore be presented in a user-friendly format to
enable decision makers to interpret and use it for decision-making. Charts, maps and
graphs convey the message better than complex tables and narratives.
o Comprehensiveness: Data should be comprehensive with enough details to allow for
decision making. A pharmacist would need to be informed on not only the type of
drug that went out of stock but also the form of drug, e.g. syrup, tablets or injectables.
o Simplicity: The process of data collection and analyses should therefore be fairly
simplified and only the necessary data should be collected on a daily basis. It should
always be borne in mind that the majority of lower level health worker have had no
training in statistics.
o Accessibility: Information emanating from the data should be accessible to managers
at all levels to facilitate decision–making, and stored properly for easy retrieval. It
should reach the manager in a timely manner, depending on the type of decisions
made.

o Provides quick view of data presented in different form.
o Numerical data are often presented in histograms
o Are similar to bar charts however the difference is that in histogram ‗the bars‘ are
connected (as long as there is no gap between the data where as in bar charts the bars
are not connected as the different categories are distinct entitles)
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 18
o Useful for numerical data if you want to show Trend over time
o It is easy to show two or more distribution in one graph as long as difference between
lines are easy to distinguish e.g. age distribution between males and females
STEP 4: Use of Data Presentation Methods (35 minutes)
Activity: Buzzing (5 minutes)
ASK students to pair up and buzz on the following question for 2 minutes
ALLOW few pairs to respond and let other pairs to add on points not mentioned
WRITE their response on the flip chart/board
CLARIFY and SUMMARIZE by using the content below
Conditions in which the following methods of data presentation are used
o Frequency distributions are used for both qualitative and quantitative data.
o A frequency distribution of data can be shown in a table or graph.
o Some common methods of showing frequency distributions include frequency tables,
histograms or bar charts.
o A frequency table is a simple way to display the number of occurrences of a particular
value or characteristic.
o Statistical hypothesis testing is founded on the assessment of differences and
similarities between frequency distributions
o In Cross tabulation
o In Cumulative frequency
o Useful in expressing the relative frequency of survey responses
o In Comparison of groups
o As a fraction
o In advertisement, e.g. shops advertise discounts on products. These discounts are
percentages
o A proportion is simply a statement that two ratios are equal.
o Uses cross products to find a missing term in a proportion
o Used when administering medication
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 19
o A ratio is a numerical expression which indicates the relationship in quantity, amount
or size between two or more parts. Example the ratio of males to females is 22:33, or 2:3.
o A rate is the quantity, amount or degree of a
disease or event measured over a specified period
o Commonly used rates in the health sector
are:
Birth Rate – The number of live births per 1000 population over a period of one
year
Death Rate – The number of deaths per 1000 population over a period of one
year
Infant Mortality Rate (IMR) – The number of deaths of infants under one-year
deaths of age per 1000 live births over a period of one year
Maternal Mortality Rate (MMR) – The number of maternal pregnancy-related in
one year per 100,000 total births in the same year
Incidence Rate – The number of new cases per population over a specific period
of time (usually a year)
Prevalence Rate – The number of existing cases per population over a specific
period of time (usually a year)
o Graph:
Line graphs can also be used to compare changes over the same period of time for
more than one group.
Bar graphs are used to compare things between different groups or to track
changes over time (trends)
The purpose of a graph is to present data that are too numerous or complicated to
be described adequately in the text and in less space
o Tables:
Show the number of times that data with certain characteristics occur in a data set
Tells how many or what proportion of a group has each value or range of value
out of all possible values
o Pie charts:
Pie charts are best to use when you are trying to compare parts of a whole. They
do not show changes over time.

A table is a drawing having columns and rows that facilitate representation of large
amount of data in an attractive easy to read and organized manner.
Steps to make a table
o Name your table – write a title of the table at the top of the paper
o Decide how many rows and columns you need
o Insert/draw a table using the computer
o Label your columns and rows
o Record the data you have in the columns and rows
o When making cross-tabulations, check that the column and row counts correspond to
the frequency counts for each variable.
o Also check that the grand total in the table corresponds to the number of subjects in the
sample. Example of a table
Table 1.: Type of health worker by residence
Residence Type of Health Worker Total
Doctors Pharmacists
Rural 10 (16%) 69 (38%) 79 (33%)
Urban 51 (84%) 113 (62%) 164 (67%)
Total 61 (100%) 182 (100%) 243 (100%)
o A line graph is a diagram that shows a line joining several points, or a line that shows
the relationship between the points.
o A line graph can be taken as xy plane, where there will be an independent variable
and a dependent variable
o It specifies how the two variables are related to each other and vary with respect to
one another.
o Mostly, the independent variable is taken on the x-axis while the dependent variable
on the y-axis.
o Step 1: Use the data from the table to choose an appropriate scale
The table given below shows the weights of a child in months
SNo. Age in Months Weight (Kg)
A. 1 38
B. 3 41
C. 5 43
D. 7 49
E. 9 51
F. 11 54
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 25
o Step 2: Draw and label the scale on the vertical and horizontal axis
o Step 3: List the each item and locate the points on the graph
o Step 4: Connect the points with line segments
follows:
Line graph have one or more lines plotted on the graph. They are very useful for showing change over time
o Bar graph is drawn on an x-y graph and it has labeled horizontal or vertical bars that
show different values.
contrasting the size of the different categories of the data provided
school 90%, 100% and 60% during the year 2000, 2001 and 2002 respectively
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 26
o The frequency polygon has most of the properties of a histogram, with an extra
feature
o Here the mid-point of each class of the x-axis is marked
o Then the midpoints and the frequencies are taken as the plotting point
o These points are connected using line segments
o We also complete the graph, that is, it's closed by joining to the x-axis.
o Frequency polygon gives a less accurate representation of the distribution, than a
histogram, as it represents the frequency of each class by a single point not by the
whole class interval
o Let‘s consider a data table and let‘s try to draw frequency polygon of it
o Draw a graph by using data given below:
Class interval Frequency
0-10 1
10-20 3
20-30 6
30-40 4
40-50 2
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 27
Step 1: First we need the mid-point of the class interval
Class interval Mid-point Frequency
0-10 5 1
10-20 14 3
20-30 25 6
30-40 35 4
40-50 45 2
Step 2: Then draw frequency polygon
o Histogram is the most accurate graph that represents a frequency distribution
o In the histogram the scores are spread uniformly over the entire class interval
o The class intervals are plotted on the x-axis and the frequencies on the y-axis
o Each interval is represented by a separate rectangle
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 28
o To plot this take the class limits on the x-axis and the frequency on the y-axis.
o On the x-axis, the scale can be 10 units whereas on the y-axis the scale can be 1 unit.
STEP 4: Interpretation of Tables and Graphs (30 minutes)
Activity: Brainstorming (10 minutes)
Ask students to brainstorm on the following question:
ALLOW few students to respond?
WRITE their responses on the flip chart/ board
CLARIFY and SUMMARISE by using the content below
o A frequency shows the number of times that data with particular characteristics occur
in a data set.
o The distribution tells how many or what proportion of the group has each value or a
range of values out of all possible values
o the frequency of each group is represented by the length of the corresponding bar
o the height of the bar over a period represents the figure for the corresponding period
o read erected rectangles over class interval representing the frequencies of the class
interval
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 29
o the frequency distributions of each grouped data by areas (height and width), e.g. the
frequency distribution of patients presenting with a certain condition in a given
period, with the patient grouped into 5-years block
o compare individual category with the total
o depicts each category as a slice of pie with the size of each slice varying according to
its proportion of the whole pie
o see variations in increase and decrease over time or seasons

CLARIFY and SUMMARISE by using the content below
Research can be classified into several categories according to the nature and purpose of the
study and other attributes.
o Applied research which is also referred to as an action research,
o Basic research also called fundamental or pure research.
Descriptive, analytical and Experimental studies or interventional studies
o Descriptive research usually involves surveys and studies that aim to identify the
facts.
o In other words, it deals with the ―description of the state of affairs as it is at present‖,
and there is no control over variables in descriptive research.
o Observational or Analytical research uses facts or information already available and
analyze these in order to make a critical evaluation of the material‖.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 38
o Experimental or interventional studies are ones where researchers introduce an
intervention and study the effects. Experimental studies are usually randomized,
meaning the subjects are grouped by chance. Randomized controlled trial (RCT):
Eligible people are randomly assigned to one of two or more groups.
o Two groups; Exploratory and Conclusive.
o Exploratory studies only aim to explore the research area and they do not attempt to
offer final and conclusive answers to research questions.
o Conclusive studies, on the contrary, aim to provide final and conclusive answers to
research questions.
o Quantitative or qualitative

___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 39
Uses
o Basic research aims to improve scientific theories for improved understanding or
prediction of natural or other phenomena.
o Applied research, in turn, uses scientific theories to develop technology or techniques
to intervene and alter natural or other phenomena.
o Though often driven by curiosity, basic research fuels applied science's innovations.
Limitations
o Does not usually generate findings that have immediate applications in a practical
level.
o Fundamental research is driven by curiosity and the desire to expand knowledge in
specific research area
Uses
o Operations research is a discipline that deals with the application of advanced
analytical methods to help make better decisions.
o It uses scientific processes and knowledge as the means to achieve a practical or
useful result
o Uses knowledge and skills in creative ways to solve complex problems and have an
impact on critical decisions
Limitations
o Costly: Operation Research (OR) is very costly.
o Not realistic: Operation Research experts make very complex models for solving
problems. These models may not be realistic
o Complex: Operation Research is a complex concept
Uses
o Provides statistical, mathematical, or numerical results
o Tends to analyze phenomena in terms of trends and frequencies
o Quantitative research is based on the measurement of quantity or amount.
o It is applicable to phenomena that can be expressed in terms of quantity.
o Quantitative research is inquiry into an identified problem, based on testing a theory,
measured with numbers, and analyzed using statistical techniques.
o The goal of quantitative methods is to determine whether the predictive
generalizations of a theory hold true.
Limitations
o Research quality is heavily dependent on the individual skills of the researcher
o More easily influenced by the researcher's personal biases and idiosyncrasies.
o Rigor is more difficult to maintain, assess, and demonstrate
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 40
Uses
o Can provide full picture of answers and reasons behind them(ethnographic)
o Can be used to inform answers to social issues
o Find ways to improve qualitative things like customers satisfaction, health
professional's opinions
o It aims to develop concepts that aid in the understanding of natural phenomena with
emphasis on the meaning, experiences and views of the students
Limitations
o Time consuming process
o Labour intensive approach in sorting, coding data etc
o Observer may be biased when interpreting
o Not easy to make comparison
o No result verification in qualitative research
Uses
o It is a small-scale study of relatively short duration, which is carried out when little is
known about a situation or a problem.
o It may include description as well as comparison.
o Used for Small scale studies
o Gathers information about unfamiliar phenomenon
o Results give insight to a problem before a large-scale study is designed
Limitations
o Interpretation of findings is judgmental
o Uses small samples which may not be representative
Uses
o involves describing the characteristics of a particular situation, event or case
o Can be carried out on a small or large scale
o Small scale, descriptive case studies
o provide quite useful insight into a problem
o Less expensive
village
Analytical
Uses
o An analytical study attempts to establish causes or risk factors for certain problems.
o Is done by comparing two or more groups some of which have or develop the
problem and some of which have not
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 41
o Describe phenomena, and
o Analyze relationship between phenomena and other variables
(determinants/association
Limitations
o Only describe phenomena: e.g. Person, Place, Time
o Low response rate
Comparative or analytical studies
An analytical study attempts to establish causes or risk factors for certain problems. It
compares two or more groups, some of which have or develop the problem and some of
which have not It uses Cross-sectional comparative studies, Case-control studies and
Cohort studies
Analytical studies
Cross-sectional studies
Uses
o Quick and cheap
o Can reveal various exposures, as first step in investigating the cause
o Repeated measures can depict(represent) trend
o Data useful in assessing health care needs
Limitation
o Not possible to determine if the exposure preceded the outcome
Cross-sectional comparative studies
Uses
o Aim at describing phenomenon and compare groups or determine factors influencing
the phenomenon
o Done at one point in time
o Measurement of exposure and effect are done at the same time
o Quick and cheap,
o Can elucidate various exposures, as first step in investigating cause,
o Repeated measures can depict trend,
o Produce data useful in assessing health care needs
Limitations
o Not possible to determine if the exposure preceded the outcome (temporal
relationship)
Case-control studies
In a case-control study the investigator compares one group among whom the problem
that he wishes to investigate is present (e.g. adverse drug reactions) and another group
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 42
called a control or comparison group, where the problem is absent, in order to find out
what factors have contributed to the problem
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 43
Uses
o Useful for generating/ test hypothesis
o Cheap and quick
o Makes use of comparison (control group)
o Can study more than one risk factor
o Useful for rare disease or long latent period
Limitations
o Data on exposure might be inaccurate and biased
o Difficult to make precise selection of control group
o Retrospective – cannot separate cause and effect
o Cannot be used for rare exposure
o You cannot calculate incidence (you do not know when disease occurred
o In a cohort study, a group of individuals that is exposed to a risk factor (study group)
is compared to a group of individuals not exposed to the risk factor (control group)
o Aim at determining risk factors for diseases/outcome
o At the start identify two groups
With exposure to a risk factor (exposed)
Without exposure (no-n exposed)
Both groups have not developed the disease/outcome at the start
Follow over time
At the end, analyses disease/outcome occurrence in both groups and compare
Limitations
o Needs to get complete and accurate information about exposure and outcome for all
individuals
o Time consuming, expensive
o Inefficient in evaluating rare diseases
o Loss of follow up affect validity of results
STEP 4: Appropriate Study Type for the Research Proposal (20 minutes)
Depending on the existing state of knowledge about a problem that is being studied, different
types of questions may be asked which require different study designs. Some examples are
given in the following matrix.

recommendations
Writing Introduction to Research Proposal
This is written when all sections of the proposal have been completed. The introduction leads
the reader from a general subject area to a particular topic of inquiry.
It establishes the scope, context, and significance of the research being conducted by
summarizing current understanding and background information about the topic, stating
the purpose of the work in the form of the research problem supported by:
o a hypothesis or a set of questions,
o explaining briefly the methodological approach used to examine the research
problem,
o highlighting the potential outcomes your study can reveal, and
o outlining the remaining structure and organization of the paper
Think of the introduction as a mental road map that must answer for the reader these four
questions:
o What was I studying?
o Why was this topic important to investigate?
o What did we know about this topic before I did this study?
o How will this study advance new knowledge or new ways of understanding?
According to Reyes, there are three overarching goals of a good introduction:
o First, ensure that you summarize prior studies about the topic in a manner that lays a
foundation for understanding the research problem
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 52
o Second, explain how your study specifically addresses gaps in the literature,
insufficient consideration of the topic, or other deficiency in the literature
o third, note the broader theoretical, empirical, and/or policy contributions and
implications of your research
STEP 5: Key Points
Operational research focuses on priority problems, it is action-oriented, uses multi-
disciplinary approach, is participatory, should be timely and cost effective,
Operational research is done systematically step by step and there are several steps to be
followed when implementing it.
STEP 6: Evaluation

Handout 8.1: Research Problem Identification
Problem Identification
o Finding a problem is not difficult but identifying one for the purpose of research is not
always easy.
o Identifying a problem situation is the first essential step in designing a research
proposal, but it must then be followed by a process of problem definition.
o The research problem identified must be defined in terms of its occurrence, intensity,
distribution, and other measures for which data are already available.
o The aim is to determine all that is currently known about the problem and the reason
it exists.
o All research is set in motion by the existence of a problem.
o A problem is a perceived difficulty, a feeling of discomfort about the way things are,
or a discrepancy between what someone believes should be the situation and what the
situation is in reality.
o While problems are the initiating force behind research, not all problems require
research.
o A potential research situation arises when three conditions exist:
A perceived discrepancy exists between what is and what should be.
A question exists about why there is a discrepancy.
At least two possible and plausible answers exist to the question.
discrepancy, then a research situation does not exist.
Problem Justification
o After the problem is identified, it is necessary next to justify the importance of the
problem. Research often is expensive and time consuming.
o Find out why the problem you wish to study is important.
Ask yourself the following questions: Can you justify your selection of the research
problem? Can you convince others that the problem is important?
What to Do: Justifying the Selection of a Research Problem
o In justifying the importance of a research problem, it is helpful to ask yourself a series
of questions and then try to answer each of them.
Is the problem you wish to study a current and timely one?
Does the problem exist now? How widespread is the problem? Are many areas
and many people affected by the problem?
Does the problem affect key populations, such as youth, people living with
HIV/AIDS (PLHA), mothers, or children?
Does the problem relate to ongoing program activities?
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 62
Does the problem relate to broad social, economic, and health issues, such as
unemployment, income distribution, poverty, the status of women, or education?
Who else is concerned about the problem? Are top government officials
concerned? Are medical doctors or other professionals concerned?
o Review your answers to these questions, and arrange them into one or two paragraphs
that justify the importance of the research problem.
o Start by discussing the broad issues that justify the problem and then begin to focus
on the more specific issues related to a particular population group or geographical
setting.
Sample Research Problem Justification
o Over time, millions of HIV-infected people in Africa and elsewhere in the world are
developing HIV-related illnesses. In most African countries, hospitals, clinics, and
other formal health care institutions simply cannot cope with the large numbers of
people in need of physical care and social and psychological support.
o In some hospitals, well over half of the beds are already occupied by AIDS patients.
In some countries the figure is as high as 70 percent of all hospital beds. This is a
problem of great concern to health care planners, as well as to the Ministry of
Finance, which simply does not have the resources to build new facilities or train
large numbers of new providers.
o The problem of providing care and support for PLHA is particularly challenging in
rural areas because there are relatively few health facilities or adequately trained
providers available. In this situation, an alternative is to provide care, support, and
treatment in the homes of those with AIDS. How to do this in a cost-effective manner
while simultaneously providing high-quality services is a challenge.
o New models of delivering care and support services in rural areas need to be
developed and tested to improve the quality of life for PLHA.
o Without effective new approaches, large numbers of people with AIDS will suffer
physical and psychological pain that might otherwise be avoided or at least lessened.
Comments on the Sample Justification:
o The first paragraph establishes the dimensions of the problem. The large number of
people with AIDS cannot be adequately treated or supported by the formal health care
system, which is already overwhelmed in many countries.
o The second paragraph notes that the problem is particularly acute in rural areas, where
health facilities and providers are relatively few in number. An alternative is to
provide services to PLHA in their homes. The important question is how to do this.
o The paragraph ends by saying that without the development of new approaches to
care and support, large numbers of PLHA will needlessly suffer.

PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 63
Handout 8.2: Examples of Research and Non-Research Problems
Example of a Non-Research Problem
o A recent situation analysis assessment of a hospital in District A found that 125 HIV
positive adults were coming to the hospital every day as part of a DOTS program to
take medication for tuberculosis (TB). But last month‘s service statistics from the
hospital‘s DOTS program revealed that for one entire week, none of the 125 patients
received any medication.
o Discrepancy
All 125 patients should be receiving a daily treatment for TB, but all 125 did not
receive a single treatment for an entire week last month.
o Problem Question
What factor or factors are responsible for 125 patients‘ failing to receive any
treatment for their TB for an entire week?
o Answer
During the week when the patients did not receive daily TB treatments, a very
heavy rainstorm caused flooding that washed out several roads and destroyed a
major bridge that is used to bring supplies to the district hospital. Because of the
flooding and the destroyed bridge, the hospital ran out of TB medication, and a
resupply truck could not reach the hospital for one week while the bridge was
being repaired.
In this example, a problem situation exists, but the reason for the problem is
already known. Therefore, assuming that all the facts are correct, there is no
reason to conduct research on the factors associated with the break in the supply
of daily TB medication for 125 patients.
Nonetheless, there may very well be a need to conduct research on the question of
why the supply logistics system is incapable of providing medication during the
rainy season, when it is known that roads and bridges are frequently damaged.
o A recent provincial study revealed great differences among villages in the
prevalence of HIV-positive persons. Despite the fact that all villages receive the
same level of health education and services from the Ministry of Health, some
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 64
villages have an HIV prevalence rate as high as 32 percent among adults from 15
to 49 years old, while other villages have a rate as low as 6 percent.
o Discrepancy
In a relatively small geographic area, you would expect that all villages should
have approximately the same sero-prevalence rate but, in fact, there is great
variation among villages.
o Problem Question
Which factors are responsible for the geographic variation in HIV prevalence
among villages?
o Possible Answers
Villages differ in their socioeconomic environments, and these differences
influence the context within which HIV is transmitted.
Some are stable agricultural villages, while some are mobile fishing
communities.
Some villages are located on major roads and have easy access to market
towns; others are more remote with very difficult access to market centers.
Some villages
have schools, health clinics, electricity, and a good water supply, while others
do not have these advantages.
context within which sexual relations take place and HIV is transmitted.
prevention, care and support programs.
change and condom distribution programs.
substantial stigma and discrimination associated with HIV/AIDS.
PLHA organizations, and effective orphan care NGOs.
individual
commitment to and institutional support for HIV/AIDS programs affect the
sexual behavior of individuals, the use of condoms, the level of stigma and
discrimination, and the transmission of HIV.
o While the problem situation presented above is clear, the possible and plausible
reasons for the problem are complex. Several of these reasons have been
described, but it is very likely there are many more.
o In situations such as this one, the researcher must devote considerable time and
attention to identifying and clearly defining the problem situation before any
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 65
potential solutions to the problem can be tested experimentally through a
longitudinal operations research study.
o The aim of clearly identifying and defining a problem situation is to focus the
research on the most important aspects of a problem that can be changed through a
program intervention.
Handout 8.3: Prioritizing Health Problems for Operational Research
Relevance
o The topic you choose should be a priority problem.
o Questions to be asked include:
How large or widespread is the problem?
Who is affected?
How severe is the problem?
o If you do not consider a topic relevant, it is not worthwhile to continue rating it. In
that case you should drop it from your list.
o Try to think of serious health problems that affect a great number of people or of the
most serious problems that are faced by clinicians in the area of your work.
o Also, consider the question of who perceives the problem as important. Health
managers, health staff and community members may each look at the same problem
from different perspectives.
o Community members, for example, may give a higher priority to economic concerns
than to certain public health problems.
o To ensure full participation of all parties concerned, it is advisable to define the
problem in such a way that all have an interest in solving it. Even within villages,
opinions may differ on how important a problem is.
o It is therefore obligatory to discuss the problem with community leaders, as well as
peripheral villagers, males as well as females, rich and poor, exploring their
perceptions of the problem.
Avoidance of Duplication
o Before you decide to carry out a study, it is important that you find out whether the
suggested topic has been investigated before, either within the proposed study area or
in another area with similar conditions.
o If the topic has been researched, the results should be reviewed to explore whether
major questions that deserve further investigation remain unanswered. If not, another
topic should be chosen.
o Also, consider carefully whether you can find answers to the problem in already
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 66
available, unpublished information or just by using your common sense. If so, you
should drop the topic from your list.
Urgency of Required Solution (Timeliness)
o How urgently are the results needed for making a decision or developing interventions
at various levels (from community to policy)? Consider which research should be
done first and which can be done later.
Political Acceptability
o In general, it is advisable to research a topic which has the interest and support of the
Local/national authorities. This will increase the chance that the results of the study
will be implemented.
o Under certain circumstances, however, you may feel that a study is required to show
that the government's policy needs adjustment. If so, you should make an extra effort
to involve the policy-makers concerned at an early stage, in order to limit the chances
for confrontation later.
Feasibility
o Look at the complexity of the problem and the resources you will require to carry out
your study and time required for intervention. Thought should be given first to
manpower, time, equipment and money that are locally available.
o In situations where the local resources necessary to carry out the processes are not
sufficient, you might consider resources available at the national level. Finally,
explore the possibility of obtaining technical and financial assistance from external
sources.
Applicability of Possible Results/Recommendations
o Is it likely that the recommendations from the study will be applied? This will depend
not only on the management capability within the team and the blessing of the
authorities but also on the availability of resources for implementing the
recommendations.
o Likewise, the opinion of the potential clients and of responsible staff will influence
the implementation of recommendations.
Ethical Acceptability
o We should always consider the possibility that we may inflict harm on others while
carrying out research or any intervention.
o Therefore, consider important ethical issues such as:
How Cultural sensitivity must be given careful consideration.
Informed consent be obtained from the research subjects.
Will the condition of the subjects be taken into account? For example, if
individuals are identified during the study who require treatment, will this
treatment be given?
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 67
What if such treatment interferes with your study results?
Scales for rating research topics
These criteria can be measured by the following rating scales:
o Relevance
o Avoidance of duplication
o Urgency
acceptable
o Political Acceptability
o Feasibility
o Applicability
o Ethical acceptability

Handout 9.1 Formulating the problem Statement
Importance of a Well-Defined Problem
o A poorly defined research problem leads to confusion.
o A well-defined research problem statement leads to:
Statement of research objectives
Hypotheses
Definition of key variables
Selection of a methodology for measuring the variables
Foundation for the further development of the research proposal
Ease in finding find information and reports of similar studies from which your
own study design can benefit
Systematic justification for undertaking the proposed research, and what the
researcher he/she hope to achieve with the study results
This is important to highlight when you present your project to community
members, health staff, relevant ministries and donor agencies who need to support
your study or give their consent.
Statement of the Problem Includes:
o Identification, definition, and justification of the research problem
o One of the most important first tasks of research is to identify and clearly define the
problem you wish to study.
o If you are uncertain about the research problem or if you are not clear in your own
mind about what you want to study, others who read your proposal will also be
uncertain.
o Problem Identification and definition
o While it is always possible to guess why a problem exists, guesses are often wrong
and usually do not provide a firm basis for designing a research study.
o A far better way to define a problem situation is to review relevant literature, examine
current service statistics, seek educated opinions from persons concerned about the
problem, and obtain probable reasons for the problem from social, economic, or
health theory.
o Follow this general procedure when identifying and defining a problem situation:
Start with a simple statement of the problem situation.
Add details as you review the literature, review theoretical concepts, and
investigate the problem in greater depth.
Simplify the focus by identifying the most important aspects of the problem that
are researchable.
Make a first attempt at identifying the problem situation by using the following format:
o Problem Situation: Write a small, simple paragraph that identifies the problem.
o Discrepancy: State the discrepancy between what is and what should be.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 77
o Problem Question: Write down the central problem question.
o Possible Answers: Write two or more plausible answers to the problem question.
From the available research literature, health and behavioral theory, current service
statistics, educated opinions and other sources of information, try to add details to the
problem situation you have just identified. Look for theoretical concepts and operational
variables that you may have missed. List these concepts and variables on a piece of paper
as you come across them. Try to answer
the following questions:
o What are the incidence and prevalence of the problem?
o Which geographic areas are affected by the problem? Which population groups are
affected by the problem?
o What are the findings of other research studies?
o What has been done to overcome the problem in the past?
o How successful were past efforts to overcome the problem?
o What seem to be major unanswered questions about the problem?
With the information you have collected from a literature review and other sources,
rewrite your statement identifying and defining the problem. Use the format described
above:
o Problem Situation, Discrepancy, Problem Question, and Possible Answers
o Add details that help to define the problem but organize the information. Try to
establish the boundaries of the problem.
o Focus your attention on the most important, researchable aspects of the problem.
Have one or more colleagues read your final statement identifying and defining the
problem situation. If they are unclear about the problem situation or cannot describe the
discrepancy between what is and what should be, then go back to the beginning and start
all over again.

o Publications (books which compile research information, journals (hard or electronic
copies)
o Unpublished information [grey literature) e.g. Dissertation, research reports not in
journals, computer data base
o Supervisors and fellow students
Sources could be at different levels of administrative system
o Community level, district and regional levels and provincial level
o National levels – e.g. national libraries, Ministries of Health, central statistics, etc.
o International levels – UNICEF, WHO, USAID, etc.; including computerized search
for international literature

PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 83
STEP 4: Summarizing Important Information Obtained from Index Cards
(55 minutes)
Strategy 1: What to do with identified information
o Read through
o Summarize the content relevant to your study (use index card)
Note pertinent information
Title of article
Author
Title of Journal/Book, Page, Year, etc (see later)
Aim of study
Methodology
Major findings
Utility of information
Write the literature review section
Prepare list of references
Strategy 2: What to do with identified information
o Organize in groups of related information/themes
Africa-Tanzania
o Write coherently using your own words (be writing not citing); use past tense
o Cite sources properly using recommended style
Writing a Literature Review
o Organize your notes in groups of related statements according to which aspect of the
problem they touch upon (e.g., community factors, service factors, etc.).
o Use your problem analysis diagram as a framework (and adapt the diagram in turn as
you find more literature).
o Decide in which order you want to discuss the various issues.
Where Do You Put Which Information?
o Some literature can be used to describe the local context (district, region, country) or
problem.
o All facts mentioned need a source, except some general and well known statements.
o For the description of the selected problem, use all available raw or published
literature.
o Literature from other countries or regions may be used to illustrate your point.
If these sources are many, you may have a separate section on international
literature.
o More complex studies using theoretical models should have a separate section
discussing
these models, which could come after the section of statement of the problem.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 84
o When drafting the background section or the statement of the problem, usually do not
describe sources one by one. Instead, write a coherent discussion in your own words,
using all relevant literature linked to each other.
o It is possible to cite several sources for one statement. Reference all the literature
referred to in your review.
o At the end of your paper, list your references in order, using the format described
above.
o In research proposals, the references come before the annexes.
o Select one style of references (such as Vancouver, Harvard, etc.) and use it
consistently for citations and reference lists in your proposal.
Bias in Literature
o Bias: A distortion of the available information in such a way that it reflects opinions
or conclusions which do not represent the real situation.
o Understanding the various types of bias helps to be critical of the existing literature.
o If you have reservations about certain references or if you find conflicting opinions in
the literature, then discuss these openly and critically. Such a critical attitude may
help you to avoid biases in your study.
o Common types of bias in literature include:
Playing down controversies and differences in one's own study results.
Restricting references to those that support the point of view of the author.
Drawing far reaching conclusions from preliminary or shaky research results or
making sweeping generalizations from just one case or small study.
STEP 5: Review of Literature Pertaining to Research Topic (20 minutes)
Review of literature pertaining to research topic avoiding the following:
Plagiarism (pretending information is yours) is defined as:
o An object (language, words, text, diagram, graphs, ideas)
o which has been taken from a source (books, journals, internet, not just text)
o by an agent (person, student, academician)
o without adequate acknowledgement of sources
o with or without intention to deceive
Bias in literature review
o Suppressing/omitting controversies/ conflicting opinion or differences
o Using author supportive references only
o Over concluding/ generalisation from inadequate data – one case or small study or
poor design
Such types of bias may have serious ethical implication (may affect people‘s health; take
researcher to court)
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 85
STEP 6: Key Points (05 minutes)
Literature review or search is ―a systematic and thorough search of all types of published

o It should cover the different aspects of the problem and its contributing factors in a
coherent way and in a logical sequence.
o Are clearly phrased in operational terms, specifying exactly what you are going to do,
where, and for what purpose.
o Are realistic considering local conditions.
o Use action verbs that are specific enough to be evaluated.
Examples of action verbs are, to determine, to reduce, to compare, to verify, to
calculate, to describe, and to establish.
o Avoid the use of vague non-action verbs such as, to appreciate, to understand, or to
study.
o Example of a Broad Objective: To determine factors associated with irrational
prescribing habits in district A.
o Examples of Specific objectives from the above broad objectives
To determine the magnitude of irrational prescribing habits in district A.
To identify number of drugs prescribed per prescription
To verify the availability of appropriate reference materials e.g.STG at
prescriber‘s office
To assess availability of essential drugs in the past 3 months
o It is ideally a prediction of an expected relationship between one or more factors and
the problem under study which can be tested.
o Are appropriate for field intervention or evaluation studies.
o Exploratory studies do not normally require hypothesis because they generally do not
test relationships between variables.
o Two types of research hypothesis are Null hypothesis and Alternative hypothesis
o A Null Hypothesis is the one that is stated in negation form. It indicates that there is no
relationship between variables. It is donated as (Ho). Example: Improved prescribing
habits have no effect in rational use of drugs
Alternation hypothesis (working hypothesis) is stated to indicate the actual
expectation.
It is donated as (H1).
Improved prescribing habits improves rational use of drugs.
o The Null Hypothesis denies the existence of any significant differences between any
compared values and stresses that even when such differences are observed, they have
occurred by chance.
o The Alternative Hypothesis is formulated in a way as to reject the null hypothesis.
o It states that there is a significant cause of the observed differences between
compared values and that the difference did not happen by chance.

STEP 5: Preparation of Research Objectives in an Appropriate Format for
the Developed Project (35 minutes)
Take care that the objectives of your study:
o Cover the different aspects of the problem and its contributing factors in a coherent
way and in a logical sequence
o Are clearly phrased in operational terms, specifying exactly what you are going to do,
where, and for what purpose;
o Are realistic considering local conditions; and
o Use action verbs that are specific enough to be evaluated
Examples of action verbs are to determine, to compare, to verify, to calculate, to
describe, and to establish
Avoid the use of vague non-action verbs such as: to appreciate, to understand, or
to study
o It is not necessary to develop an objective for every single contributing factor
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide 93
STEP 6: Development of Research Questions Appropriate for the Study
(25 minutes)
Research question: Statement that identifies the phenomenon, situation or certain
Characteristics to be studied?
It's essential to develop a research questions that you're interested in or care about in order
to focus your research
For example,
o Researching a broad topic such as "business management" is difficult since there may
be hundreds of sources on all aspects of business management.
o On the other hand, a focused question such as "What are the pros and cons of
Japanese management style?" is easier to research and can be covered more fully and
in more depth.
o How do you develop a usable research question?
Choose an appropriate topic or issue for your research, one that actually can be
researched
Then list all of the questions that you'd like answered yourself.
Choose the best question, one that is neither too broad nor too narrow.
Sometimes the number of sources you find will help you discover whether your research
question is too broad, too narrow, or okay?
If you know a lot about the topic, you can develop a research question based on your own
knowledge. If you feel you don't know much about the topic, think again.
It's a good idea to evaluate your research question and to ask for feedback on your
research question.
Once you complete your list, review your questions in order to choose a usable one that is
neither too broad nor too narrow.
In this case, the best research question is "three"
o Question "one" is too narrow, since it can be answered with a simple statistic
o Question "two" is too broad; it implies that the researcher will cover many tactics for
reducing the problem of irrational drug use that could be used throughout the country
o Question "three," on the other hand, is focused enough to research in some depth
STEP 7: Key Points (5 minutes)
Writing introduction to research proposal leads the reader from a general subject area to a
topic of inquiry
The general objective of a study states what is expected to be achieved by the study in
general terms Specific objectives explain the broad objective in specific

objective:
o To explore to what extent Community Home-Based Care (CHBC) projects in
Tanzania provide adequate, affordable and sustainable care of good quality to people
with HIV/AIDS, and to identify ways in which these services can be improved.
o It was split up in the following specific objectives:
To identify economic, psychosocial and other needs of patients and their families
affected by AIDS.
To determine the extent to which formal and informal support systems address
these needs from the viewpoint of service providers as well as patients.
To determine the economic costs of CHBC to the patient and family as well as to
the formal CHBC programme.
To relate the calculated costs to the quality of care provided to the patient by the
family and to the family/patient by the CHBC programme.
To determine how improved CHBC and informal support networks can contribute
to the needs of persons with AIDS and other chronically and terminally ill
patients.
To use the findings to make recommendations on the improvement of CHBC to

ASK students if they have any questions before continuing
STEP 2: Definition of Common Terms Used in Sampling (20 minutes)
o For studies which involve only small numbers of people all of them can be included
in the investigation.
o For research which focuses on a large population, for practical reasons, it is only
possible to include some of its members in the investigation. It is important to draw a
sample from the total population.
Sampling unit
o A single section selected to research and gather statistics of the whole.
o For example, when studying a group of college students, a single student could be a
sampling unit.
o Unit of selection in the sampling process, e.g. Person, a school, a household, etc.
Sampling frame
o a list of units from which a sample is to be picked
Sampling fraction (sampling ratio)
o a proportion of sampling units to be picked from a specified sampling frame
number of units in sampling frame
Sampling interval
o An interval at which units are picked from a sampling frame when systematic
sampling is done.

STEP 3: Identifying the Population (s) to be Studied (20 minutes)
Activity: Buzzing (5 minutes)
ASK students to pair up and buzz on the following question for 2 minutes
‘What is study population?
ALLOW few pairs to respond and let other pairs to add on points not mentioned
WRITE their response on the flip chart/board
CLARIFY and SUMMARIZE by using the content below
Study population
o Collective of study units for which the values of the varieties of interest could
possibly be determined.
o In identifying the population(s) to be studied we must consider the following questions:
What is the group of people (STUDY POPULATION) we are interested in from
which we want to draw a sample?
How many people do we need in our sample?
How will these people be selected?
Sample is a subset of study population selected to participate in the research when
whole study population cannot be reached
o The study population has to be clearly defined (for example, according to age, sex, and
residence.) Otherwise we cannot do the sampling
o Each study population consists of STUDY UNITS. The way we define our study
population and our study unit depends on the problem we want to investigate and on the
objectives of the study
o If researchers want to draw conclusions which are valid for the whole study
population, which requires a quantitative study design, they should take care to draw a
sample in such a way that it is representative of that population.
o A representative sample has all the important characteristics of the population from
which it is drawn

STEP 4: Common Methods of Sampling (35 minutes)
Activity: Small Group Discussion (20 minutes)
DIVIDE students into small manageable groups
ASK students to discuss on the following question
ALLOW students to discuss for 10 minutes
ALLOW few groups to present and the rest to add points not mentioned
CLARIFY and SUMMARIZE by using the contents below
The common methods of sampling are:
Two types of sampling probability and non-probability
o Non-probability
o Probability (random sampling)
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
107
o Involves using random selection procedures, to ensure that each unit of the sample is
chosen on the basis of chance.
o All units of the study population should have an equal, or at least a known chance of
being included in the sample.
o Requires listing of all study units exist or can be compiled. This listing is called the
sampling frame.
o Simple random sampling
o Systematic sampling
o Stratified sampling
o Cluster sampling
o Multistage sampling
To select a simple random sample, you need to:
o Make or search for an existing numbered list of all the units in the population from
which you want to draw a sample (sampling frame).
o Decide on the size of the sample.
o Select required number of sampling units, using a lottery method.
o For example, a simple random sample of 50 students is to be selected from a school of
250 students. Using a list of all 250 students, each student is given a number (1 to
250), and these numbers are written on small pieces of paper. All the 250 papers are
put in a box, after which the box is shaken vigorously, to ensure randomization. Then
50 papers are taken out of the box, and the numbers are recorded. The students
belonging to these numbers will constitute the sample.
o Individuals are chosen at regular intervals (for example every fifth) from the sampling
frame.
o Ideally a number to tell where to start selecting individuals from the list is randomly
selected.
For example, a systematic sample is to be selected from 1200 students of a school. The
sample size selected is 100. The sampling fraction is:
The sampling interval is therefore 12.
The number of the first student to be included in the sample is chosen randomly
o If it is important that the sample includes representative study units of small groups
with specific characteristics, then sampling frame must be divided into groups, or
strata, according to these characteristics.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
108
o For example, residents from urban and rural areas, or different religious or ethnic
group
o Random or systematic samples of a pre-determined size will have to be obtained from
each group (stratum).
o The selection of groups of study units (clusters) instead of the selection of study units
individually.
o Clusters are often geographic units (e.g. districts, villages) or organizational units (e.g.
clinics, training groups).
o A multi-stage sampling procedure is carried out in phases and it usually involves
more than one sampling method. Example selecting one region out of 26 then select 4
councils out of 7 in the selected region. In the 4 selected councils, the researcher
selects 3 wards out of 8 then two villages are selected from the 3 wards. The selection
method in each stage could be random or systematic.

PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
109
o Unequal chance of being included in the sample (nonrandom)
o It is a sampling process in which the samples are selected for specific purpose with a
predetermined basis for of selection
o Purposeful sampling strategies for qualitative studies
o Extreme case sampling
o Maximum variation sampling
o Homogeneous sampling
o Critical case sampling
o Snowball or chain sampling
o Sample Size in Qualitative Studies
There are no fixed rules for sample size in qualitative research.
The size of the sample depends on what you try to find out, and from what
different informants or perspectives
o If you want to explore how you can involve mothers in your HC catchment area
you try to find that out. For example:
effectively in early detection and treatment of pneumonia, you might decide to
conduct some FGDs to assess mothers‘ knowledge, attitudes and practices with
respect to antimalarials.
You could start with two FGDs among lowly educated mothers and two among
mothers with more education (who usually are of higher socio-economic status).
o If research objective is more complex e.g., attitudes of males and females towards
family planning, and has policy implications for a larger area, your sample will be
bigger. You might start with four FGDs, two among males and two among females,
subdivided according to socio-economic status.
possible, but not determined.
o The desirable sample size depends on the expected variation in the data (of the most
important variables).
o The more varied the data are the larger the sample size needed to attain the desired
level of accuracy.
o After conducting FGDs and in-depth interviews in the study on attitudes of men and
women towards family planning you might decide to conduct a bigger survey.
o If the exploratory study revealed that age and education appear to be important factors
determining FP use, compare FP use in groups with different levels of education and

of different ages.
o If you split each of these variables up in three categories, and you select four
categories of informants (male users/ spouses of female users; female users; male
non-users, female non-users) you would have 12 cells in each table. In order to obtain
5-10 answers per cell you would require 60-120 informants in each research area.

o The bigger the non-response rate, the more necessary it becomes to take remedial
action.
o It is important in any study to mention the non-response rate and to honestly discuss
whether and how the non-response might have influenced the results.
o Studying volunteers only: The fact that volunteers are motivated to participate in the
study may mean that they are also different from the study population on the factors
being studied.
o It is better to avoid using non-random selection procedures that introduce such an

short illness episodes and mild cases.
characteristics in different seasons of the year. For this reason, data should be collected on
the prevalence and distribution of malnutrition in a community during all seasons rather
than just at one point in time.
o Data collection tools (including written introductions for the interviewers to use with
potential respondents) should be pre-tested. If necessary, adjustments should be made
to ensure better co-operation.
o If non-response is due to absence of the subjects, follow-up of non-respondents may
be considered.
o If non-response is due to refusal to co-operate, an extra, separate study of non-
respondents may be considered in order to identify to what extent they differ from
respondents.
o Another strategy is to include additional people in the sample, so that non-respondents
who were absent during data collection can be replaced. This can only be justified if
their absence was very unlikely to be related to the topic being studied.
o The bigger the non-response rate, the more necessary it becomes to take remedial
action.
o It is important in any study to mention the non-response rate and to honestly discuss
whether and how the non-response might have influenced the results.
STEP 7: Key Points (5 minutes)
Sampling is the process of selecting a number of study units from a defined study
population
BIAS in sampling is a systematic error in sampling procedures which leads to a distortion
in the results of the study

the sample size depends on the type of problem investigated, required precision and to a
certain extent, the resource available
If your research objective is more complex e.g., attitudes of males and females towards

Very few studies use the whole population (Census)
Most studies use a subset of a population (Sample)
How big should a sample be?
Too large or too little sample is unethical:
Too large: waste resources
Too little: Inconclusive results

study:
o The desirable sample size depends on the expected variation in the data (of the most
important variables): the more varied the data are, the larger the sample size we would
need to attain the desired level of accuracy.
o The desirable sample size also depends on the number of cells we will have in the
cross-tabulations which we need to analyze the results.
A rough guideline is to have at least 5 to 10 study units per cell
o How big can be calculated. Still, the desirable sample size cannot always be achieved
for lack of resources such as time, manpower and money.
This constraint applies to quantitative as well as qualitative studies
Therefore, the eventual sample size is usually a compromise between what is
desirable and what is feasible
o Sample size calculations
` The following steps should be taken:
Estimate how big the proportion might be (say 80%)
Choose the margin of error you will allow in the estimate of the proportion (say +
10%). This means that, if in the survey indeed 80% of the children are found to be
vaccinated, this proportion will probably be between 70 and 90% in the whole
study population from which the sample was drawn.
Choose the precision with which you want to be confident that the vaccination
coverage in the whole population is indeed between 70 and 90%. You can never be
100% sure. Do you want to be 95% sure? Or 99%?

STEP 4: Determination of Sample Size(s) Most Appropriate for the
Research Design (Feasible) (35minutes)
The feasible sample size determination
o Is not calculated, depends on available resources (human, time, money, transport)
Availability of finance: in practice, size of the sample depends upon the amount of
money available for the study purposes. This factor should be kept in view while
determining the size of sample for large samples result in increasing the cost of
sampling estimates
o Depends on expected variation in the data: the more varied the data are, the larger the
sample size one would need to attain the same level of accuracy
o Depends on the number of cells one will have in the cross-tabulations required to
analyze the result
A rough guideline is to have at least 20-30 study units per cell
o Eventual sample size – is a compromise between desirable and feasible
o Nature of study: If items are to be intensively and continuously studied, the sample
should be small. For a general survey the size of the sample should be large, but a
small sample is considered appropriate in technical surveys.
o Type of sampling: Sampling technique plays an important part in determining the size
of the sample. A small random sample is appropriate to be much superior to a larger
but badly selected

o Violating informants‘ right to privacy, by posing sensitive questions or by gaining
access to records which may contain personal data.
o Observing the behavior of informants without them being aware
o Allowing personal information (which informants would want to be kept private) to

be made public.
o Failing to observe/respect certain cultural values, traditions or taboos valued by your
informants. Using human biological tissue, using human in trial of drugs.
o Obtaining informed consent before the study or the interview begins.
o Do not explore sensitive issues before a good relationship has been established with
the informant.
o Ensure the confidentiality of the data obtained.
Learning enough about the culture of informants to ensure it is respected during the
o data collection process.
If sensitive questions are asked, for example, about family planning or sexual
practices, or about opinions of patients on the health services provided, it is advisable
to omit names and addresses from the questionnaires.
o Inform participants that they are free to withdraw from the study at any point

Health research coordination in Tanzania is under the Medical Research Coordinating
Committee (MRCC). MRCC is the national health research coordinating body that
ensures all health research follows the national health ethics requirements.
Procedure for research ethical clearance
o The whole process of receiving, reviewing and approving the protocols takes a
maximum of 6 weeks
o National Health Research Ethics Committee (NatHREC) carries research monitoring
by on-site visits in collaboration with district and regional medical authorities.
In this regard, copies of certificates of cleared research proposals are sent to
respective District and Regional Medical Officers where research is to be carried out.
o Research certificate approval is renewed annually, and PIs are required to submit
progress reports biannually.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
126
o To publish the findings, the principal investigator will have to seek permission from
the National Institute for Medical Research.
o All proposed health research in Tanzania must get an Institutional Ethical approval at
the host institution where the research will be based.
o In case there is no any Institutional Ethics Committee, the approval will be sought
from the NatHREC.
o For all health research involving external collaborators (non-Tanzanians), the
researchers must apply for the Institutional Ethical Clearance as well as the National
Ethics Clearance.
o Non-Tanzanian researchers are required by law to get Research Clearance and
Research Permit from the Tanzania Commission for Science and Technology
(COSTECH) (www.costech.or.tz).
o Protocols for Clinical trials to be conducted in Tanzania are reviewed by another
specialized sub-committee, Clinical Trials Sub-Committee.
This sub-committee has nine members and meets monthly and reports to the
NatHREC.
o Clinical trials are required to also obtain a Clinical Trials Certificate from Tanzania
Food and Drug Authority (www.tfda.or.tz) before the commencement of the study.
Application procedures
o Applicants for research clearance are required to submit application form, Curriculum
vitae, Research proposal and three passport size photographs preferably two months
before commencement of research.
o Permits are given for a period of one year and can be renewed for similar period
provided satisfactory progress reports for the previous periods are received by
COSTECH.
o If and when these formalities have been satisfactorily completed (which may take
several months) applicant will receive a formal written offer of a research clearance.
o Applicant should not make any irreversible preparations to leave for Tanzania unless
and until he/she receives this offer letter.
o Soon after obtaining a research permit, the researcher will be required to proceed to
the Immigration Department and apply for class C residence permit.
STEP 5: Key Points (5 minutes)
Research Ethics is defined here to be the ethics of the planning, conduct, and reporting of
research
As we develop our data collection techniques and implement research, we need to
consider whether our research procedures are likely to cause any physical or emotional
harm

o Analysis is time-consuming and requires experience; otherwise important data
may be
Lost
o Thoroughly train and supervise the interviewers or select experienced
research assistants.
o Prepare a list of further questions to keep at hand to use to probe for
answer(s) in a
systematic way.
o Pre-test open-ended questions and, if possible, pre-categorize the most
common responses
o In interviews questions are often asked as open-ended questions, but to
facilitate
___________________________________________________________________________

135
recording and analysis, some answers can be pre-categorized. For example:
‘How did you become a member of the Village Health Committee?’
Details stated:
1. Volunteered…………………………………………………………………………….. �
2. Elected at a community meeting…………………………………………………. �
3. Nominated by community leaders…………………………………………………�
4. Nominated by the health staff……………………………………………………… �
5. Other (specify): …………………………………………………………………………………………..�
In this case the first four categories of answers are known, but there may be
other possibilities.
Therefore, there is a category ‘other’ where other answers can be
recorded. During the analysis, these responses can still be further
categorized.
o For open-ended questions, more than one answer is usually allowed.
o Answers can be recorded quickly
o Analysis is easier
o If one pre-categorizes too early, a lot of interesting and valuable information
may never be recorded or may end up in the category ‘other’.
o Interviewers may try to force the information into the categories that are listed
and, by
merely ticking, this additional valuable information will be lost.
o Interviewers may stop after receiving the first answer, whereas more than one
response could be applicable.
o Sometimes, if the respondent hesitates in answering, the interviewer may be
tempted to present some possible answers, thereby causing bias.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
136
o Frequently, questionnaires have very little space for recording full responses
under “other”, forcing the interviewer to write down a response that
summarizes the respondent’s answer, thereby losing valuable information.
o Clear guidelines have to be provided to interviewers on important issues
For example: If a question leads to an interesting discussion, it should be
completely written down
o Interviewers should be trained to solicit discussion
o Categorize questions for which all possible categories of responses are
known, e.g., some health practices (Antimalarial use: currently using, ever
used, and never used).
o These questions, when used, will always be followed by other questions
asking for elaboration on reasons and conditions for use or non-use of the
practice.
o Closed questions have a list of possible options or answers from which the
respondents must choose.
o Closed questions are most commonly used for background variables such as
age, marital status or education, in case of age and education take the exact
values and categorize them during data analysis.
For example:
What is your opinion on the following statement: (Circle one response).
Women who are pregnant do not use antimalarial

waste
time obtaining more information than one needs.
For example:
may ask:
o Did you eat any of the following foods yesterday?’ (Circle yes if at least one
item in
each set of items is eaten.)
Peas, beans, lentils Yes No
Fish or meat Yes No
Eggs Yes No
Milk or cheese Yes No
Insects Yes No
o It saves time
o Comparing responses of different groups, or of the same group over time,
becomes easier
o In case of illiterate respondents, the interviewer may be tempted to read the
list of
possible answers in the given sequence, thereby influencing the choice of
response and introducing bias.
o Take objectives and variables as a starting point.
o Decide what questions will be needed to measure or (in the case of qualitative
studies) to define your variables and reach your objectives.
o Formulate one or more questions that will provide the information needed for
each
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
138
variable.
o Check whether each question measures one thing at a time.
o Avoid leading questions.
A question is leading if it suggests a certain answer.
For example: Do you think that people have to give bribes at hospital X to
be seen by a doctor? Hardly leaves room for ‘no’ or for other options.
A better question would be: Have you recently visited hospital X?
This would be followed by a series of other probing questions such as:
o Ask sensitive questions in a socially acceptable way.
Questions relating to abortion, sexual practices of adolescents, or AIDS
and mental illness in the family are usually sensitive.
o Sequencing the questions: design your interview schedule or questionnaire to
be
‘informant friendly’.
The sequence of questions must be logical for the informant and allow, as
much as possible, for a ‘natural’ conversation, even in more structured
interviews.
o A separate, introductory page is attached to each questionnaire, explaining
the
purpose of the study, requesting the informant’s consent to be interviewed
and
assuring confidentiality of the data obtained.
o Each questionnaire has a heading and space to insert the number, date and
location of
the interview, and, if required, the name of the informant.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
139
o Layout is such that questions belonging together appear together visually.
o If the questionnaire is long, use subheadings for groups of questions.
o Sufficient space is provided for answers to open-ended questions, categories
such as
‘other’ and for comments on pre-categorized questions.
on the right
half of the page).
o If interviews will be conducted in one or more local languages, the
questionnaire
should be translated in order to standardize the way questions will be asked.
o After having it translated you should have it retranslated into the original
language by
a different person.
o Compare the two versions for differences and make decisions concerning the
final
o phrasing of difficult concepts.
o All steps discussed above apply to written questionnaires as well as to
guides/questionnaires used in interviews.
o Self-administered questionnaires are most commonly used in large-scale
surveys using predominantly pre-categorized answers among literate study
populations.
o In exploratory studies which require intensive interaction with informants in
order to gain better insight in an issue,
o Written questionnaires may sometimes be useful in small-scale studies on
sensitive

PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
140
topics.
They are usually combined with other tools e.g. FGD on sensitive issues like sexual
behavior.
o Checklists can be used to systematically observe human behavior or the
condition of
specific equipment (e.g. fridge, expiring dates of medicines, or completeness
of records).
o Observations can be relatively open or can be predetermined comparisons of
reality
against fixed standards.
o The objectives of the study determine the content of a checklist.
o A checklist includes all the items or points that must be considered during an
observation in the field, or when extracting data from existing records.

in a conclusive way. Example of haphazard data collection: During a nutrition survey
three different weighing scales were used in three villages.
o The researchers did not record which scales were used in which village.
o After completion of the survey it was discovered that the scales were not standardized
and indicated different weights when weighing the same child.
o It was therefore impossible to conclude in which village malnutrition was most
prevalent.
o Reviewing documents
o Observing/observation
o Interviewing (face-to-face)
o Administering written questionnaires
o Focus group discussions
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
142
o Documents to be reviewed can be obtained from dispensary, health center,
and hospital records.
For example:
o Analysis of the information routinely collected by health facilities can be very
useful for identifying problems such as flows of drug supply or dispensing
o Other sources of data may be:
Health Information Management System, census,
Unpublished reports and publications in archives and libraries or in offices,
Newspapers and published case histories
o It is inexpensive, because data is already there
o It Permits examination of trends over the past
o Data are not always easily accessible
o Ethical issues concerning confidentiality may arise
o Information may be inaccurate or incomplete
o Observation is a technique that involves systematically selecting, watching
and recording behavior and characteristics of living beings, objects or
phenomena
o Observation of human behavior is a much-used data collection technique
o It can be undertaken in different ways:
Participant observation: The observer takes part in the situation he or she
observes
For example, a doctor hospitalized with a broken hip, who now observes
hospital procedures from within.
o Non-participant observation: The observer watches the situation, openly or
concealed,
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
143
but does not participate.
o Observation becomes a scientific tool and method of data collection for the
researcher, when:
It serves a formulated research purpose.
Is systematically planned and recorded.
Is subjected to checks and controls on validity and reliability
o Subjective bias is eliminated, if observation is accurately done
o The information relates to what is currently happening
o Not complicated by either past behavior or future intentions or attitudes.
o Independent of respondent’s willingness to respond and hence less
demanding on active cooperation on the part of the respondents
o Suitable in studies which deal with subjects who are not capable of giving
verbal reports of their feelings for one reason or the other
o It is an expensive method
o Information provided by this method is very limited
o Sometimes unforeseen events may interfere with the observational task
o Some subjects are rarely accessible to direct observation
o If subjects know that they are being observed, they may change their behavior
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
144
o An interview is a data-collection technique that involves oral questioning of
respondents, either individually or as a group
o Requires a person known as the interviewer asking questions in a face-to-
face contact to the interviewee or through other means of communication like
telephone
o Answers to the questions posed during an interview can be recorded by
writing them
down (either during the interview itself or immediately after the interview) or by
tape-recording the responses, or by a combination of both
o Detailed information can be obtained
o Interviewer could overcome resistance of the respondent, if any.
Provides flexibility to the interviewer to restructure, clarify, or add probe
questions
Observation can also be applied during interview
Is suitable for use with both literates and illiterates
Has higher response rate than written questionnaires
The interviewer can collect supplementary information about the
respondent’s personal characteristics and environment.
o It is very expensive and time consuming especially when the sample is large
o Chances of Interviewer as well as interviewee’s bias are high
o People with certain high-level positions like officials or executives may not be
easily
approachable under this method and to that extent the data may prove
inadequate
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
145
o Creating effective rapport with the interviewee may be a difficult
o Some subjects may demand incentives during data collection process
o There may be a language barrier between an interviewer and interviewee
o Interviewers should be carefully selected and trained
o They must possess technical competence (interviewing and interpersonal
skills)
o They should be able to create an atmosphere of trust and confidence
o A written questionnaire (also referred to as self-administered questionnaire) is
a data
collection method in which written questions are presented that are to be
answered by the respondents in written form. The questions can be either
open-ended or closed (with pre categorized answers).
o A written questionnaire can be administered in different ways, such as by:
Sending questionnaires by mail with clear instructions on how to answer
the questions
and asking for mailed responses;
Gathering all or part of the respondents in one place at one time, giving
oral or written instructions, and letting the respondents fill out the
questionnaires; or
Hand-delivering questionnaires to respondents and collecting them later
o Low cost when study is large
o Free from interviewer bias
o Respondents have adequate time to give out their answers
o Respondents, who are not easily approachable, can be reached
o Used in large studies
o Permits anonymity and may result in more honest responses.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
146
o Low rate of return of the duly filled in questionnaires
o Bias due to non-response is undetermined
o Used only when respondents are educated and cooperating
o Control over questionnaire may be lost
o Not flexible once the questionnaire has been dispatched out
o Ambiguous replies or omissions creating difficult in interpretation
o Slowest method of all when mailing is used
o FGD allows a group of 6 – 12 informants to freely discuss a certain subject
with the guidance of a facilitator or reporter during which group members talk
freely and spontaneously about a certain topic.
o Characteristics and Uses of Focus Group Discussions
A FGD is a qualitative method.
A FGD aims to be more than a question-answer interaction.
The idea is that group members discuss the topic among themselves, with
guidance from the facilitator.
o FGD techniques can be used to:
Focus research and develop relevant research hypotheses by exploring in
greater
depth the problem to be investigated and its possible causes.
Formulate appropriate questions for more structured, larger scale surveys.
Develop appropriate messages for health education programmes and later
evaluate the messages for clarity
Explore controversial topics. For example: Sexual behavior is a
controversial topic in the sense that males and females judge sexual
relations and sexuality often from very different perspectives.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
147
o Advantages of FGD
The researcher can interact with the participants, pose, follow up
questions or ask
questions that probe more deeply.
Results can be easier to understand than complicated statistical data.
The researcher can get information from non-verbal responses such as
facial expressions or body language.
Information is provided more quickly than if people were interviewed
separately.
o The small sample size means the groups might not be a good representation
of the larger population
o Group discussions can be difficult to steer and control, so time can be lost to
irrelevant topics
o Respondents can feel peer pressure to give similar answers to the
moderators’ questions
o The moderator’s skills in phrasing questions along with setting can affect
responses and skew results

Bias: Is a distortion in the collected data so that it does not represent reality
o Defective instruments
Questionnaires
Fixed or closed questions on topics about which little is known (often
asking the ‘wrong things’).
Open-ended questions without guidelines on how to ask (or to answer)
them vaguely phrased questions
Leading questions that cause the respondent to believe one answer
would be preferred over another or questions placed in an illogical order
o Weighing scales or other measuring equipment that are not standardized
o These sources of bias can be prevented by:
Carefully planning the data collection process
By pre-testing the data collection tools
o Observer bias
Can easily occur when conducting observations or utilizing loosely
structured group or individual interviews.
There is a risk that the data collector will only see or hear things in which
she or he is interested or will miss information that is critical to the
research.
o Effect of the interview on the informant
The informant may mistrust the intention of the interview and avoid certain
questions or give misleading answers.
For example: in a survey on alcoholism you ask school children: ‘
Does your father sometimes get drunk?’ Many will probably deny that he
does, even if it is true
o Such bias can be reduced by:
Adequately introducing the purpose of the study to informants.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
149
Phrasing questions on sensitive issues in a positive way.
Taking sufficient time for the interview and by assuring informants that the
data collected will be confidential.
o Information bias
Sometimes the information itself has weaknesses.
Medical records may have many blanks or be unreadable. This tells
something about the quality of the data and has to be recorded.
For example, in a compliance of TB drugs study the percentage of non-
compliant patient with an incomplete or missing address should be
calculated.
o Another common information bias is due to gaps in people’s memory this is
called
memory or recall bias.
For example: A mother may not remember all details of her child’s last
diarrhea
episode and of the treatment she gave two or three months afterwards.
For such common diseases it is advisable to limit the period of recall, asking,
for
example, ‘Has your child had diarrhea over the past two weeks?’
STEP 4: Preparation for Data-Collection Tools (45 minutes)
Questionnaires and interview schedules are used to collect information for quantitative
research
The steps of designing them are the same even though they are used for different data
collection techniques; i.e. Self-administered questionnaire and interviewing respectively
Before designing questionnaires consider the following:
o Study objectives and variables
o Be clear of what you want to know or measure.
o Ascertain whether all required information is going to be obtained by questioning
only or not
o How much is known about the problem being investigated. Familiar? Unfamiliar?
his determines whether closed/open questions should be used.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
150
o The number of subjects to be studied. This determines how much of open/closed
questions to be used
Open-ended (free response) questions: respondents are not given options to choose; theyy
answer in their own words
Closed questions (fixed alternatives): respondents are given alternative answers to choose
from
o Should measure the variable under study
o Should be ones to which respondents are expected to know the answers
o Should be clear and unambiguous
o phrased in simple language; avoid technical terms
o Contain one idea only
o Should not be offensive
o Should not suggest an answer (leading)
o first step: Deciding on the content
Refer to the study objectives and variables
Think of the question(s) needed to measure the variable
o Second step: Formulating the questions
Formulate one (or more) question (s) that will provide the required information
Make sure that the questions satisfies the requirements discussed earlier
o Third step: Sequencing the questions
Arrange them in a logical sequence to allow a natural discussion (consumer
friendly)
Begin with non-sensitive questions and pose the sensitive ones later
o Fourth step: Formatting the questionnaire
Questionnaires normally have two major sections
Introductory section. This precedes the questions and have the following contents
o Questions section. This bears the questions and the following should be
ensured
Related questions should appear together
There is sufficient space for respondents to fill in their responses to open-ended
questions
The boxes for pre-categorized responses are placed in consistent manner
There are reserved boxes for computer coding for computer aided data analysis
Formatting should ensure that the questionnaire is user friendly
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
151
o Fifth step: Translation
Translation of the questionnaire into language familiar to all respondents should
be done if the original version is in a different language.
o Sixth step: Pretesting
Before embarking on actual data collection,, it is important to check whether the
questionnaire gathers the information expected and whether both the interviewer
and interviewee feel at ease with it.
o Designing data collection forms involves
Step 1: Clarifying the specific needs of your application
Step 2: Identifying the information you want to work with
Step 3: Then devising a design that best meets your need
o A checklist is a tool for identifying the presence or absence of conceptual knowledge,
skills, or behaviors
o Developing a checklist involves the following steps
Step 1: Review the learning outcome and associated criteria for success
State the level of success required for the checklist to be considered completed, In
most cases, all items must be checked
Decide on the response such as ―Yes‖ or ―No‖, or simply have a box to be
checked once the item has been completed
Step 2: From a procedure, process, or task description list, pick those items that
are required for a good performance or product
completion of the task
Step 4: Write clear instructions for the observer
Step 5: Review the task descriptions for details and clarity
Step 6: Format the checklist
Step 7: Ask for feedback from other instructors before using it with learners
o Checklists are used for identifying whether key tasks in a procedure, process, or
activity have been done in complete and in a systematic manner.
STEP 5: Conducting an Interview (35 minutes)
Activity: Brainstorming (10 minutes)
Ask students to brainstorm on the following question:
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
152
ALLOW few students to respond?
WRITE their responses on the flip chart/ board
CLARIFY and SUMMARISE by using the content below
o The interviewer-informant relationship and interview conditions
o An interviewer needs to have the skills of turning an informant into a partner
Partnership between interviewer and informant implies that the interviewer will try to
minimize the social distance between him/herself and the informant
o a researcher has to invest in the relationship
o First she /he has to be clear to the informant about the purpose of the interview and
the study.
Enough information should be given to raise the interest of informants and to
enable them to judge whether they would like to participate or not.
Consent has to be obtained before the interview
o Second: Interviewers should try to blend in the environment. In order to do so:
Clothing of interviewers should be culturally acceptable and as simple as possible
Sitting arrangements for interviewer(s) and informant(s) should preferably be at
the same height
Gender relations have to be respected.
an interviewer should show interest in what the informant says, be at ease (never
in a hurry); Make the informant feel at ease
The environment should also be supportive of the interview situation.
Anything which disturbs (noise, other people listening, a formal surrounding)
should if possible be avoided
Tape recording may be an enabling or a disturbing environmental factor in the
interview
Informants should be asked for their consent before use
o Third: The interviewer‘s tasks
The interviewer has a number of other tasks:
Posing questions
Evaluating answers and probing for elaboration or more precision in case of a
superficial or invalid answer
Noting down answers
Leading the discussion, but at the same time encouraging the informant to give
spontaneous information relevant to the topic by letting him/her talk
Keeping control over the interview
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
153
At the end, the interviewer should summarize the interview
after-interview' discussions and questions should always be recorded, like all
spontaneous information, because discussions can shed light on complicated, not
yet fully clear issues from many preceding interviews.
o Fourth: Training the research team/assistants
Research assistants should be taught basic interview techniques, such as:
Asking questions in a neutral manner
Not showing by words or expression what answers one expects
Not showing agreement, disagreement or surprise
Recording answers to open questions precisely as they are provided, without
sifting or interpreting them

Handout 16.1: Overview of Data Collection Techniques
Data collection techniques refer to a variety of methods which are used to gather
information for the study.
Data collection techniques allow to systematically collect information about the objects of
study (people, objects, phenomena) and about the settings in which they occur.
In the collection of data, we have to be systematic.
If data are collected haphazardly then it will be difficult to answer research questions
in a conclusive way.
Common Data Collection Techniques in Use
o Reviewing documents
o Observing/observation
o Interviewing (face-to-face)
o Administering written questionnaires
o Focus group discussions
Reviewing Documents
o Documents to be reviewed can be obtained from dispensary, health center, and
hospital records.
For example, analysis of the information routinely collected by health facilities
can be very useful for identifying problems such as flows of drug supply or
increases in the incidence of certain diseases.
o Other sources of data may be Health Information Management System, census,
unpublished reports and publications in archives and libraries or in offices,
newspapers
and published case histories
Limitations of Reviewing Documents
o Data are not always easily accessible.
o Ethical issues concerning confidentiality may arise.
o Information may be inaccurate or incomplete.
Observation Technique
o Observation is a technique that involves systematically selecting, watching and
recording behavior and characteristics of living beings, objects or phenomena.
o Observation of human behavior is a much-used data collection technique.
It can be undertaken in different ways:
Participant observation: The observer takes part in the situation he or she
observes.
hospital procedures from within.

157
o Non-participant observation: The observer watches the situation, openly or concealed,
but does not participate.
Observation becomes a scientific tool and method of data collection for the researcher,
when:
o It serves a formulated research purpose.
o Is systematically planned and recorded.
o Is subjected to checks and controls on validity and reliability.
Advantages of Observation Method
o Subjective bias is eliminated, if observation is accurately done.
o The information relates to what is currently happening.
o Not complicated by either past behavior or future intentions or attitudes.
o Independent of respondent‘s willingness to respond and hence less demanding on
active cooperation on the part of the respondents.
o Suitable in studies which deal with subjects who are not capable of giving verbal
reports of their feelings for one reason or the other.
Limitations of Observation Method
o It is an expensive method
o Information provided by this method is very limited
o Sometimes unforeseen events may interfere with the observational task
o Some subjects are rarely accessible to direct observation
o If subjects know that they are being observed, they may change their behaviour
Interviewing Technique
o An interview is a data-collection technique that involves oral questioning of
respondents, either individually or as a group.
o Requires a person known as the interviewer asking questions in a face-to-face contact
to the interviewee or through other means of communication like telephone.

o There may be a language barrier between an interviewer and interviewee.
Pre-Requisites and Basic Tenets of Interviewing
o Interviewers should be carefully selected and trained
o They must possess technical competence (interviewing and interpersonal skills)
o They should be able to create an atmosphere of trust and confidence

the respondents in written form. The questions can be either open-ended or closed
(with pre categorized answers).
o A written questionnaire can be administered in different ways, such as by:
Sending questionnaires by mail with clear instructions on how to answer the
questions and asking for mailed responses;
Gathering all or part of the respondents in one place at one time, giving oral or
written instructions, and letting the respondents fill out the questionnaires; or
Hand-delivering questionnaires to respondents and collecting them later.
Advantages of Questionnaires
o Low cost when study is large
o Free from interviewer bias
o Respondents have adequate time to give out their answers
o Respondents, who are not easily approachable, can be reached
o Used in large studies
o Permits anonymity and may result in more honest responses.
Limitations of Questionnaires
o Low rate of return of the duly filled in questionnaires
o Bias due to non-response is undetermined
o Used only when respondents are educated and cooperating
o Control over questionnaire may be lost
o Not flexible once the questionnaire has been dispatched out
o Ambiguous replies or omissions creating difficult in interpretation
o Slowest method of all when mailing is used
Focus Group Discussions (FGD)
o FGD allows a group of 6 – 12 informants to freely discuss a certain subject with the
guidance of a facilitator or reporter during which group members talk freely and
spontaneously about a certain topic.
Characteristics and Uses of Focus Group Discussions
o A FGD is a qualitative method.
o A FGD aims to be more than a question-answer interaction.
o The idea is that group members discuss the topic among themselves, with guidance
from the facilitator.
o FGD techniques can be used to:
Focus research and develop relevant research hypotheses by exploring in greater
___________________________________________________________________________

160
depth the problem to be investigated and its possible causes.
Formulate appropriate questions for more structured, larger scale surveys.
Help understand and solve unexpected problems in interventions.
Develop appropriate messages for health education programmes and later evaluate
the messages for clarity.
Explore controversial topics. For example: Sexual behavior is a controversial
topic in the sense that males and females judge sexual relations and sexuality
often from very different perspectives.
Advantages of FGD
o The researcher can interact with the participants, pose, follow up questions or ask
questions that probe more deeply.
o Results can be easier to understand than complicated statistical data.
o The researcher can get information from non-verbal responses such as facial
expressions or body language.
o Information is provided more quickly than if people were interviewed separately.
Limitations of FGD
o The small sample size means the groups might not be a good representation of the
larger population
o Group discussions can be difficult to steer and control, so time can be lost to
irrelevant topics
o Respondents can feel peer pressure to give similar answers to the moderators‘
questions
o The moderators skills in phrasing questions along with setting can affect responses
and skew results
Advantage of using Available Information Usually there is a large amount of data that has
already been collected by others, although it may not necessarily have been analyzed or
published. Locating these sources and retrieving the information is a good starting point
in any data collection effort. For example,
o Analysis of the information routinely collected by health facilities can be very useful
for identifying problems in certain interventions or in flows of drug supply, or for
identifying increases in the incidence of certain diseases.
o Analysis of health information system data, census data, unpublished reports and
publications in archives and libraries or in offices at the various levels of health and
health-related services, this may be a study in itself. Usually, however, it forms part of
a study in which other data collection techniques are also used.
o The use of key informants is another important technique to gain access to available
information. Key informants could be knowledgeable community leaders or health
staff at various levels and one or two informative members of the target group (e.g.,
adolescents on their sexual behavior). They can be involved in various stages of the
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
161
research, from the statement of the problem to analysis of the data and development
of recommendations.
o Other sources of available data are newspapers and published case histories, e.g.,
patients suffering from serious diseases, or their relatives, telling their experiences
and how they cope.
o The advantage of using existing data is that: Collection is inexpensive. However, it is
sometimes difficult to gain access to the records or reports required, and the data may
not always be complete and precise enough, or too disorganized.
Note:
In order to retrieve the data from available sources, the researcher will have to
design an instrument such as a checklist or compilation sheet.
In designing such instruments, it is important to inspect the layout of the source
documents from which the data is to be extracted.
For health information system (HIS) data, for example, the data compilation sheet
should be designed in such a way that the items of data can be transferred in the
order in which the items appear in the source document. This will save time and
reduce error.
Interviewing
o An interview is a data-collection technique that involves oral questioning of
respondents, either individually or as a group. Answers to the questions posed during
an interview can be recorded by writing them down (either during the interview itself
or immediately after the interview) or by tape-recording the responses, or by a
combination of both.
o Interviews can be conducted with varying degrees of flexibility. The two extremes,
high and low degree of flexibility, are described below:
High degree of flexibility:
abortions, the investigator may use a list of topics rather than fixed questions.
responsibilities girls and their partners take to prevent pregnancy (if at all),
and the actions they take in the event of unwanted pregnancies.
respondent falls silent, (e.g., when asked about abortion methods used, who
made the decision and who paid).
often possible to come back to a topic discussed earlier in a later stage of the
interview.
for interviewing individuals as well as groups of key informants.
understanding of the problem or situation he is investigating, or if the topic is
sensitive. It is frequently applied in exploratory studies.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
162
o Less flexible methods of interviewing are useful when the researcher is
relatively knowledgeable about expected answers or when the number of
respondents being interviewed is relatively large.
o Then questionnaires may be used with a fixed list of questions in a
standard sequence, which have mainly fixed or pre-categorized answers.
o For example: After a number of observations on the (hygienic) behavior of
women drawing water at a well and some key informant interviews on the
use and maintenance of the wells, one may conduct a larger survey on
water use and satisfaction with the quantity and quality of the water.
Administering Written Questionnaires
o A written questionnaire (also referred to as self-administered questionnaire) is a data
collection tool in which written questions are presented that are to be answered by the
respondents in written form. A written questionnaire can be administered in different
ways, such as by:
o Sending questionnaires by mail with clear instructions on how to answer the questions
and asking for mailed responses;
o Gathering all or part of the respondents in one place at one time, giving oral or written
instructions, and letting the respondents fill out the questionnaires; or hand-delivering
questionnaires to respondents and collecting them later.
o The questions can be either open-ended or closed (with pre-categorized answers).
Projective Techniques
o When a researcher uses projective techniques, she/he asks an informant to react to
some kind of visual or verbal stimulus. For example:
An informant may be provided with a rough outline of the body and be asked to
draw her or his perception of the conception or onset of an illness.
Another example of a projective technique is the presentation of a hypothetical
question or an incomplete sentence or case/study to an informant (‗story with a
gap‘).
o A researcher may ask the informant to complete in writing sentences such as:
If I were to discover that my neighbor had TB, I would …;
If my wife were to propose that I use condoms, I would…
Or (s) he may ask the informant: Suppose your child suffered from diarrhea, what
would you do?
o Such techniques can easily be combined with semi-structured interviews or written
questionnaires. They are also very useful in FGDs to get people‘s opinion on sensitive
issues.
o Mapping and Scaling
Mapping is a valuable technique for visually displaying relationships and
resources.
In a water supply project for example:
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
163
distance of the homes from the wells, other water systems, etc. It gives
researchers a good overview of the physical situation and may help to
highlight relationships hitherto unrecognized.
stage to sampling.
categorize certain variables that they would not be able to rank themselves.
medicine and ask them to arrange these into piles according to their
usefulness. The informants would then be asked to explain the logic of their
ranking.
Mapping and scaling may be used as participatory techniques in rapid appraisals
or situation analyses. Rapid appraisal techniques and participatory research are
approaches often used in health systems research.

Handout 16.3: Focus group discussions
Uses of Focus Group Discussions
o Help understand and solve unexpected problems in interventions. For example:
In District X, the recent national (polio) immunization days (NID) showed widely
different coverage‘s per village (50-90%) and in a number of villages a marked
decrease in coverage was observed compared to last year.
Eight FGD decrease were held with villages‘ mothers, two in town, three in rural
with a marked in NID coverage and three in villages with a high coverage
throughout.
It appeared that overall; the concept NID had raised confusion.
Most people believed that this mass campaign strengthened the children‘s
immunity
Infections.
In the villages with a low NID coverage there had been a high incidence of
malaria in
died.
Mothers therefore believed that the NID campaign was useless.
Develop appropriate messages for health education programmes and later evaluate
the messages for clarity.
For example: A rural health clinic wanted to develop a health education
programme focused on weaning problems most often encountered by mothers in
the surrounding villages and what to do about them.
The focus group discussion could be used for exploring relevant local concepts as
well as for testing drafts when developing the messages.
The messages should be developed and tested in different socio-economic groups
of mothers, as weaning practices may differ with income, means of subsistence
and education of the mothers. Also ethnic differences may have to be taken into
account.
o Explore controversial topics.
For example: Sexual behavior is a controversial topic in the sense that males and
females judge sexual relations and sexuality often from very different
perspectives.
Sexual education has to take this difference into account.
Through FGDs, first with females, then with males, and then with a mixed group
to confront both sexes with the different outcomes of the separate discussions
(listed on flip charts) it becomes easier to bring these differences in the open.
Especially for teenagers, who may have many stereotypes about the other sex or
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
166
be reluctant to discuss the topic openly (particularly girls), such a ‗multi-stage‘
approach is useful.
Strengths and Limitations of FDG
o Implementation of FGDs is an iterative process; each focus group discussion builds
on the previous one, with a slightly elaborated or better-focused set of themes for
discussion.
o Provided the groups have been well chosen, in terms of composition and number (see
o below), FGDs can be a powerful research tool which provides valuable spontaneous
information in a short period of time and at relatively low cost.
o FGD should not be used for quantitative purposes, such as the testing of hypotheses or
the generalization of findings for larger areas, which would require more elaborate
surveys.
o However, FGDs can profitably complement such surveys or other, qualitative
techniques.
o Depending on the topic, it may be risky to use FGDs as a single tool.
o In group discussions, people tend to center their opinions on the most common ones,
on ‗social norms. In reality, opinions and behavior may be more diverse. Therefore it
is advisable to combine FGDs with at least some key informant and in-depth
interviews.
o Explicitly soliciting other views during FGDs should be routine as well.
o In case of very sensitive topics, such as sexual behavior or coping with HIV/AIDS,
FGDs may also have their limitations, as group members may hesitate to air their
feelings and experiences freely.
o One possible remedy is the selection of students who do not know each other (e.g.,
selection of children from different schools in FGDs about adolescent sexual
behavior), while assuring absolute confidentiality.
o It may also help to alternate the FGD with other methods, for example, to precede it
by a self-developed role play on sexual behavior, or to administer a written
questionnaire immediately after the FGD with open questions on sexual behavior in
which the students can anonymously state all their questions and problems. This
worked in Tanzania and Nepal.
How to Conduct a Focus Group Discussion
o Determine the purpose
A FGD can be regarded as a mini-study. It therefore requires one or two clear
objectives.
These objectives will guide the research team in the formulation of discussion
questions.
o Situation analysis
Any FGD requires good knowledge of local conditions. Communities are seldom
or never homogeneous. There are always differences between community
members, for example in education, political power, gender, economic status and
ethnic group.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
167
These differences will be reflected in their perceptions of the problems they suffer
from and possible solutions.
A researcher must be aware of these differences, otherwise (s)he may miss
important groups of students or obtain a hotchpotch of information.
Similarly, she/she must know which key persons or organizations could be good
entry points for the selection of students in the FGDs (e.g.: women‘s groups,
parent associations, youth clubs, etc.).
For example: In an intervention study on sexual health among out-of-school youth
in an urban area, the researcher first planned some interviews with key informants.
He selected the leaders of a political youth club and of a Christian youth club and
some teachers, with whom he thoroughly discussed his research topic.
each of the three groups, separated into boys and girls, draw maps of the town
and asked them to mark places which they thought riskful in terms of sexual
behavior (easy contacts, unprotected sex).
identify wider networks of adolescents at risk who had to be included in the
study.
Points to be Considered when Preparing the FGD
o Recruitment of students: Students should be roughly of the same socio-economic
group or have a similar background in relation to the issue under investigation. The
age and sexual composition of the group should facilitate free discussion.
o Selection of students: If you are an outsider in the research area, you may have to rely
on your key informants for the first selection of students in FGDs.
o Your key informants to whom you have explained thoroughly the purpose and the
process of the FGD might each suggest some individuals who could be invited to a
focus group discussion.
o Another way of getting students is to conveniently select individuals in a systematic
way, to try and ensure a range of views.
o You might, for example, ask every third or fourth person you find. This method might
be more suitable in urban areas.
o Physical arrangements:
Communication and interaction during the FGD should be encouraged in every
way possible. Arrange the chairs in a circle. Make sure that there will be no
disturbances, sufficient quietness, adequate lighting, etc.
Try to hold the FGD in a neutral setting which encourages students to freely
express their views. A health center, for example, is not a good place to discuss
traditional medical beliefs or preferences for other types of treatment.
Preparation of a discussion guide:
o There should be a written list of topics to be covered, formulated as a series of open-
ended questions.
o Guides for different groups gathered to discuss the same subject may vary slightly,
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
168
depending on their knowledge or attitudes and how the subject should first be
explored with them.
Conducting the session
o One of the members of the research team should act as ‗facilitator‘ or ‗moderator‘ for
the focus group discussion.
o One should serve as ‗recorder‘.
o The facilitator should preferably be as close as possible to the students in their
characteristics (same sex, roughly same age).

Handout 16.4: Function of Focus Group Facilitator
Functions of the Facilitator of the FDG ( Focus Discussion group)
o The facilitator should NOT act as an expert on the topic. His or her role is to stimulate
and support discussion.
o Introduce the session
Introduce yourself as facilitator and introduce the recorder.
Let students introduce themselves with whatever names they wish to use.
Put the students at ease and explain the purpose of the FGD, the kind of
information needed, and how the information will be used (for the planning of a
health programmes, an education programmes).
Ask permission to use a tape-recorder, let people hear their own voices before the
session starts.
You might offer drinks and allow some informal discussion before the actual
session starts.
o Encourage discussion
Be enthusiastic, lively, and humorous and show your interest in the groups‘ ideas.
Formulate questions and encourage as many students as possible to express their
views.
Remember there are no ‗right‘ or ‗wrong‘ answers.
React neutrally to both verbal and non-verbal responses.
o Encourage involvement
o Avoid a question-and-answer session. Some useful techniques include:
Asking for clarification: ‗Can you tell me more about…?‘
Reorienting the discussion when it goes ‗off the track‘: Saying: ‗Wait, how does
this relate to…?‘
Saying: ‗Interesting point, but how about…?‘
Using one student‘s remark to direct a question to another, for example, ‗Mrs. X
said …, but how about you, Mrs. Y?‘
When dealing with a dominant participant, avoiding eye contact or turning
and changing the subject.
his/her opinion, making more frequent eye contact to encourage his/her
participation is important.
o Deal correctly with sensitive issues.
o If you notice that the discussion stops when dealing with a sensitive topic, you could
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
170
o ask students (if literate) to anonymously write down their responses or opinions on the
topic.
o Alternatively, you could summarize for the group some of the opinions from previous
focus group discussions, focusing on one or two major contrasting opinions.
o Still another strategy is to form sub-groups, and to get a member of the sub-group to
summarize and present the opinions of their sub-group members after which the
whole group can still discuss these opinions.
o Build rapport, empathize
o Observe non-verbal communication.
o Ask yourself, ‗What are they saying? What does it mean to them?‘
o Be aware of your own tone of voice, facial expressions, body language, and those of
the students.
o Avoid being placed in the role of expert
o When asked for your ideas or views by a respondent, remember that you are not there
o to educate or inform.
o Direct the questions back to the group by saying: ‗What do you think‘, ‗What would
you do?‘
o Set aside time, if necessary, after the session to give students the information they
have asked for.
o Do not try to comment on everything that is being said.
o Don‘t feel you have to say something during every pause in the discussion.
o Wait a little and see what happens.
o Control the rhythm of the meeting, but in an unobtrusive way
o Listen carefully and move the discussion from topic to topic. Subtly control the time
allocated to various topics so as to maintain interest.
o If students spontaneously jump from one topic to another, let the discussion continue
for a while since useful additional information may surface; then summarize the
points brought up and reorient the discussion.
o Take time at the end of the meeting to summarize, check for agreement and thank the
Students
o Summarize the main issues brought up, check whether all agree and ask for additional
comments.
o Thank the students and let them know that their ideas have been a valuable
contribution and will be used for planning the proposed research, intervention, or
health education materials.
o Listen for additional comments and spontaneous discussions which occur after the
meeting has been closed.
Functions of the Recorder
o The recorder should keep a record of the content of the discussion as well as
emotional reactions and important aspects of group interaction.
o Assessment of the emotional tone of the meeting and the group process will enable
you to judge the validity of the information collected during the FGD.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
171
o Items to be recorded include:
Date, time, place
Names and characteristics of students
General description of the group dynamics (level of participation, presence of a
dominant participant, level of interest)
Opinions of students, recorded as much as possible in their own words, especially
for key statements
Emotional aspects (e.g., reluctance, strong feelings attached to certain opinions)
Vocabulary used – particularly in FGDs that are intended to assist in developing
questionnaires or health education materials
Spontaneous relevant discussions during breaks or after the meeting has been
closed
o It is highly recommended that a tape-recorder be used to assist in capturing
information. Even if a tape-recorder is used, notes should be taken as well, in case the
machine malfunctions and so that information will be available immediately after the
session for discussion.
o If there is no reliable tape-recorder available, it is advisable to have two recorders.
o A supplementary role for the recorder could be to assist the facilitator (if necessary)
by drawing his or her attention to: missed comments from students missed topics (the
recorder should have a copy of the discussion guide during the FGD)
Number and Duration of Sessions
o Number of sessions. The number of focus group sessions to be conducted depends
upon project needs, resources, and whether new information is still coming from the
sessions, (that is, whether contrasting views within and between various groups in the
community are still emerging). If not, you may stop.
o One should plan to conduct at least two FGDs for each sub-group (for example, two
for males and two for females). Otherwise you have no way of assessing whether the
information you get from the first FGD is representative for that group.
Duration
o A focus group session typically lasts up to an hour and a half.
o Generally, the first session with a particular type of group is longer than the following
ones because all of the information is new.
o Thereafter, if all the groups have a similar opinion on particular
topics, the facilitator may be able to move the discussion along more quickly to other
topics which still elicit new points of view.

SESSION CONTENTS
STEP 1: Presentation of Session Title and Learning Tasks (5 minutes)
READ or ASK students to read the learning tasks and clarify
ASK students if they have any questions before continuing
STEP 2: Typical Problems that May Arise During Data Collection and
Solutions (15 minutes)
Activity: Buzzing (5 minutes)
ASK students to pair up and buzz on the following question for 2 minutes
ASK What problems may arise during data collection and their solutions
ALLOWS few students to respond
WRITE their responses on the flipchart or board
CLARIFY and SUMMARIZE by using the content below
Sources of data distortion (bias) that might include:
o Deviations from the sampling procedures set out in the proposal.
o Variability or bias in observations or measurements made because
Research assistants are placed under too much stress
Inadequate supervision of research assistants.
Questionnaire not filled in completely
o Training research assistant
o Pretest instrument
o Adequate supervision of data collection
o Revise method to check quality of data
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
183
o Prior anticipation of problems that might occur and prepare plan to overcome them
STEP 3: Preparation of a Plan for Data Collection for the Developed
Research Proposal (10 minutes)
o Listing the tasks that have to be carried out, and who should be involved,
o Making a rough estimate of the time needed for the different parts of the study
o Identifying the most appropriate period in which to carry out the research.
o Scheduling the different activities that have to be carried out each week in a
work plan.
o Before the proposal development is finished, a pre-test of the data collection
and data
analysis procedures should be made.
o The advantages of conducting a pre-test before the proposal is that we can
draft the work plan and budget based on more realistic estimates, as well as
revise the data collection tools before we submit the proposal for approval.
o However, further pre-testing and planning of the research have to be done in
the field.
o Stage 1: Permission to proceed
o Stage 2: Data collection
o Stage 3: Data handling
o Consent must be obtained from the relevant authorities, individuals and the
community in which the project is to be carried out.
This may involve organizing meetings at national or provincial level, at
district and at village level.
o For clinical studies this may also involve obtaining written informed consent.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
184
o The principal investigator will be responsible for obtaining permission to
proceed at the various levels.
o The Health Research Unit in the Ministry of Health or the institution organizing
the
course may assist in obtaining permission from the national level.
o During data collection consider:
Logistics: who will collect what, when and with what resources
Quality control (data must be reliable and valid)
o When allocating tasks for data collection, it is recommended that first list type
of data
required.
o Identify who could best implement each of the tasks.
If it is clear earlier that your research team will not be able to carry out the
entire
study by itself
Plan to look for research assistants to assist in relatively simple but time-
consuming tasks.
Consider the following:
o Think about how long will it take to collect data for each component of the
Study?
The time required to reach the study area(s)
The time required locating the study units (persons, groups, records),
search for
specific informants (e.g., users or defaulters of a specific service)
It might take more time to locate informants than to interview them;
consider the number of visits required per study unit.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
185
o Calculate the number of interviews that can be carried out per person per day
o Calculate the number of days needed to carry out the interviews. For
example: You need to do 200 interviews
o Since the research team usually consists of very busy people, it is unlikely
that team
members can spend more than 30 working days on the entire study:
o 5 days for preparation (including pre-testing and finalizing questionnaires)
o 20 days actual field work
o 5 days data processing + preliminary analysis
the
demands of the project will determine the actual time needed for the data
collection
o Availability of research team members and research assistants
o The appropriate season(s) to conduct the field work (if the problem is season-
related
or if data collection would be difficult during certain periods)
o Accessibility and availability of the sampled population
o Public holidays and vacation periods
o Develop a clear procedure for handling and storing data
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
186
o Number questionnaires and other research tools. Decide if this should be
done at the time of the interview or at the time the questionnaires are stored.
o Each tool used will get its own numbers starting from 1. If some data sets are
linked,
e.g., you interview leprosy patients as well as their relatives and neighbors to
analyze
their interaction and possible stigma from different perspectives, better link the
numbers.
o Identify the person responsible for storing data and the place where it will be
stored.
o Decide how data should be stored.
o Record forms should be kept in the sequence in which they have been
numbered. In what sequence should data be collected?
o Other issues to consider during data collection
In general, it is advisable to start with analysis of data that is already
available.
data to be drawn from different sources but in one locality should be
collected at the same time.
It is extremely important that the data collected are of good quality (reliable
and valid).
o Deviations from the sampling procedures set out in the proposal.
o Variability or bias in observations or measurements made because:
Subject changes his/her behavior
Use of unstandardized weighing scales or inaccurate or no guidelines for
interviewing.
Variation in researchers’ observations (observer variability) in what they
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
187
observe or measure.
Variations in criteria for measurement or for categorizing answers;
changed them during the study.
o Prepare a field work manual for the research team as a whole, including:
o Guidelines on sampling procedures and what to do if respondents are not
available or to co-operate.
o A clear explanation of the purpose and procedures of the study which should
be used to introduce each interview
o Instruction sheets on how to ask certain questions and how to record
STEP 4: Determination of Various Tasks of the Staff Needed for Research
(25 minutes)
Activity: Small Group Discussion (5 minutes)
DIVIDE students into small manageable groups
ASK students to discuss on the following question
ALLOW few students to respond
WRITE their responses on flipchart or board
CLARIFY and SUMMARIZE by using the contents below
the following matrix.

Task To be carried out by
Reviewing record (hospital + HCs) Research team, with research assistant
Focus group discussions with health staff
Research team
before and after individual staff interviews
Individual health staff interviews Research team
Shadowing RCH nurses Principal investigator
Interviews with mothers (community-based)
Research team, with research assistants
before and after delivery
STEP 5: Preparation of a Work Schedule (Gantt chart) (25 minutes)
o Review and revise, if necessary, the list of tasks you prepared for your plan for data
collection.
o Add to the list other tasks you must complete not related to data collection (such as
clearance of proposal; data analysis and report writing; and feedback to authorities
and target group).
o Number all tasks.
o Make revisions, if required
o Preparing a work schedule (Gantt chart)
o Step 1: Consider:
The time required to reach the study area(s);
The time required to locate the study units (persons, groups, records);
If you have to search for specific informants (e.g., users or defaulters of a specific
service) it might take more time to locate informants than to interview them.)
The number of visits required per study unit.
for example, follow-up of pregnant mothers or malnourished children
Time needed for follow-up of non-respondents should also be considered.
o Step 2: Calculate the number of interviews that can be carried out per person per day
o Step 3: Calculate the number of days needed to carry out the interviews.
For example:
you need to do 200 interviews
your research team of 5 people each can do 4 interviews per day
you will need how many days for the interviews
o Step 4: Calculate the time needed for the other parts of the study, (for example, 10
days)

What are the important points to be considered when starting to plan for data collection?
ALLOW few pairs to respond and let other pairs to add on points not mentioned
WRITE their response on the flip chart/board
CLARIFY and SUMMARIZE by using the content below
The most important points to be considered when starting to plan for data collection:
o It should be simple, realistic, and easily understood by those directly involved.
o It should cover the preparatory and the implementation phases of the project, as well
as data analysis, reporting, dissemination and utilization of results.
o The activities covered should include training, technical or research tasks;
administrative, secretarial and other support tasks.
o The realities of local customs (local holidays, festivals) and working hours should be
considered, when preparing the work plan.
o Also, seasonal changes and their effect on travel, work habits, and on the topic you
are studying (such as incidence of disease or nutritional status), should be kept in
mind as the schedule is planned.

CLARIFY and SUMMARIZE by using the contents below
o A detailed budget will help to identify which resources are already locally available
and
which additional resources may be required.
o The process of budget design will encourage you to consider aspects of the work plan
you
have not thought about before
o Serve as a useful reminder of activities planned, as your research gets underway.
o A complete budget is not prepared until the final stage of project planning.
Cost is usually a major limiting factor and therefore must always be kept in mind
during planning so that your proposals will not have an unrealistically high
budget.
o Remember that both ministries and donor agencies usually set limits for research
project
o budgets.
o The use of locally available resources increases the feasibility of the project from a
financial
point of view.
o Funds for personnel allowances for researchers, and assistants during training
research
assistants, field work piloting and actual study
o Funds for secretarial services e.g. typing the proposal and questionnaires, final report
and
dissemination
o Funds for transport number of visits and kilometers to be covered, funds for supplies.
o Stationary and lunch for those attending FGD, meetings
o 5% for emergency
o Do not underestimate the time needed to complete project tasks in ‗the real world‘.
o Include a 5% emergency fund if you fear that you might have budgeted for the
activities
rather conservatively.
If inclusion of a contingency fund is not allowed, an alternative is to slightly over-
budget in major categories.
o It is not sufficient to present a budget without explanation.

o The budget justification follows the budget as an explanatory note justifying briefly,
in the context of the proposal, why the various items in the budget are required.
o Give clear explanations concerning why items that may seem questionable or that are
particularly costly are needed and discuss how complicated expenses have been
calculated.
If a strong budget justification has been prepared then, it is less likely that
essential items will be cut during proposal review.
o Explore whether other health-related institutions are willing to temporarily assign or
second personnel to the project.
o When possible, use local rather than outside personnel. If consultants are needed at
the
beginning, train local personnel as soon as possible to take over their work.
o Explore the use of students or community volunteers, where appropriate.
o Plan for strict control of project expenditures, such as those for vehicle use, supplies.

o Most donor organizations have their own special project forms, which include a
budget format (budget format)
o Keep in mind the tendency to underestimate the time needed to complete project tasks
in ‗the real world‘
o If the budget is for a period longer than a year, build in allowances for inflation before
the project begins and in subsequent years by increasing costs by a set percentage
(budget preparation)
o It is not sufficient to present a budget without explanation (Budget justification)
o When possible, use local rather than outside personnel to reduce cost
Obtaining funding for projects
o To conduct research, it is usually necessary to obtain funding for the research project.
In addition to preparing a good research proposal, the following strategies are useful
for researchers who need to obtain their own funding:
o Familiarize yourself with the policies and priorities of funding agencies. Such
policies and priorities may be:
o Identify the procedures, deadlines and formats that are relevant to each agency.
o Obtain written approval and support from relevant local and national health
authorities and submit this together with your proposal.
o If you are a beginning researcher, associate yourself with an established researcher.
Host agencies scrutinize the ‗credibility‘ of the researcher to whom funds are
allocated. Such credibility is based on previous projects that have been successfully
completed.
o Build up your own list of successfully completed projects (i.e., your own reports,
publications, etc.).
STEP 6: Key Points (5 minutes)
Plan for data collection should be simple, realistic, and easily understood by those
directly involved.
To conduct research, it is usually necessary to obtain funding for the research project
The type of budget format to be used may vary depending upon whether the budget will
be supported by your own organization or submitted to the Ministry of Health or a donor
organization

CLARIFY and SUMMARIZE by using the contents below
Use of available information
o Means: Looking into records and extracting information
o Advantages
Cheaper since information is already there
Doesn't depend on respondent‘s willingness to respond
Allow observation of trend
o Disadvantages
May be difficult to access the data
Information may be incomplete or imprecise
Ethical concerns regarding confidentiality may arise
Observation
o Means: Watching and recording, no talking with respondent
o advantages
Gives information of what is currently happening
Doesn't depend on respondent‘s willingness to respond
Disadvantages
Observer may notice only what interests him/her (bias)
Presence of observer may influence behaviour of respondent
Ethical concerns regarding confidentiality may arise
Interview
o Means: Asking a respondent questions orally
o Advantages
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
209
Can be used for illiterates
Allows clarification of questions
Higher response rate
o Disadvantages
Expensive (time, human resources)
Presence of interviewer may influence response
Administering a questionnaire
o Means: giving respondents written questions (questionnaire) so that they read the
questions themselves and provide answers
o Advantages
Quick and cheap, no many research assistants needed
Allows anonymity, hence more honest responses
o disadvantages
Require literate respondents
Response rate could be low
Questions may be misunderstood by respondents
Some respondents may choose responses simply because they saw it there,
otherwise they wouldn't have thought of it
Focus group discussion
o Means: A discussion of a topic by a group of selected persons guided by a facilitator
o Advantages
Flexibility to explore new issues that arises
Findings are more believable
Relatively cheaper
o Disadvantage
Discussion could base on irrelevant issues
Minority opinion may not be expressed
Difficult to analyse the data
Require highly trained moderator
In-depth interview
o Means: A person to person conversation in order to gain insight into people's
thoughts, feelings, and behaviour on important issues
o Advantages
Collects large amount of data quickly
Allows clarification of issues
o Disadvantages
Needs skilled interviewer
Data difficult to analyse
Views could be subjective

STEP 5: Advantages of Using a Combination of Different Data Collection
Techniques (10 minutes)
give a more comprehensive understanding of the topic under study.
o Loosely structured interviews using open-ended questions.
o Focus group discussions.
o Participant observations are also called qualitative research techniques.
o They produce qualitative data that is often recorded in narrative form.
o Involve the identification and exploration of a number of often mutually related
variables that give insight in human behavior (motivations, opinions, attitudes), in the
nature and causes of certain problems and in the consequences of the problems for
those affected.
o In qualitative technique why, what and how are important questions.
o Quantitative technique is used to quantify the size, distribution, and association of
certain variables in a study population.
o In quantitative research techniques, how many? How often? and how significant? are
important questions.
o Structured questionnaires that enable the researcher to quantify pre- or post-
categorized answers to questions are an example of quantitative research techniques.
The answers to questions can be counted and expressed numerically.
o Example: Observation and interview
STEP 6: Difference Between Data Collection Methods and Tools (25
minutes)
Data collection instruments and tools are things that are used in collecting information.
o Example of instrument: Data compilation form, interview guide, etc.
o Example of tool: Pen, weighing scale

STEP 7: Sources of Bias in Data Collection and Ways of Preventing (15
Minutes)
o Defective instruments or tools
o Interviewers and observers – different data collectors eliciting different information
o Effect of the interview – respondents mistrust the interview intention, thus dodge the
questions
o Information bias – incomplete record, respondents being unable to recall
o Data collection tools (including written introductions for the interviewers to use with
potential respondents) should be pre-tested. If necessary, adjustments should be made
to ensure better co-operation.
o If non-response is due to absence of the subjects, follow-up of non-respondents may
be considered.
o If non-response is due to refusal to co-operate, an extra, separate study of non-
respondents may be considered in order to identify to what extent they differ from
respondents.
o Another strategy is to include additional people in the sample, so that non-respondents
who were absent during data collection can be replaced. This can only be justified if
their absence was very unlikely to be related to the topic being studied.
o The bigger the non-response rate, the more necessary it becomes to take remedial
action.
o It is important in any study to mention the non-response rate and to honestly discuss
whether and how the non-response might have influenced the results.

administering questionnaires, focus group discussion, in-depth interview
Sources of bias in data collection may arise from tools, interviewer and information
recorded

Activity: Small Group Discussion (20 minutes)
DIVIDE students into small manageable groups
ASK students to discuss on the following question
ALLOW students to discuss for 10 minutes
ALLOW few groups to present and the rest to add points not mentioned
CLARIFY and SUMMARIZE by using the contents below
o Sorting data
o Performing quality-control checks
o Data processing
o Data analysis
o An appropriate system for sorting the data is important for facilitating subsequent
processing and analysis.
o If you have different study populations (for example village health workers, village
health committees and the general population), number the questionnaires separately.
o In a comparative study sort the data right after collection into the two or three groups
that will be compared during data analysis.
o Checked in the field to ensure that all the information has been properly collected and
recorded.
o Before and during data processing, the information should be checked again for
completeness and internal consistency.
o If a questionnaire has not been filled in completely you will have missing data for
some of the variables.
___________________________________________________________________________

o If there are many missing data in a particular questionnaire, the decision may be to
exclude the whole questionnaire from further analysis.
o If an inconsistency is clearly due to a mistake made by the researcher/research
assistant

validity of the study.
excluded from further analysis. (Normally, however, you would discover such a problem
during the pre-test and change the wording of the question.)
o Have the data been sorted appropriately?
o Have questionnaires been numbered?
o Major categories of informants distinguished?
o Have quality checks been performed? For completeness and consistency of
information?
o Has all qualitative data been categorized as far as possible?
o Decide on the method for processing and analyzing data from questionnaires
Manually, using data master sheets or manual compilation of the questionnaires
By computer, for example, using micro-computer and existing software or self-
written programmes for data analysis
o Categorizing/classifying the data
o Coding
o Summarizing the data in data master sheets, manual compilation without master

o Decisions have to be made concerning how to categorize responses.
o Categorical variables that are investigated through closed questions or observation,
the categories are decided earlier.
o In interviews the answers to open-ended questions, the answers can be pre-
categorized to a certain extent, depending on the knowledge of possible answers that
may be given.
Answers that are difficult or impossible to categorize may be put in a separate
residual category called ‗others‘, but this category should not contain more than
5% of the answers obtained.

cannot reclassify the data anymore.
STEP 3: Coding the Data (20 minutes)
Activity: Brainstorming (05 minutes)
Ask students to brainstorm on the following question:
ALLOW few students to respond?
WRITE their responses on the flip chart/ board
CLARIFY and SUMMARISE by using the content below
o If the data will be entered in a computer for subsequent processing and analysis, it is
essential to develop a coding system.
o For computer analysis, each category of a variable can be coded with a letter, group of
letters or word, or be given a number. For example, the answer ‗yes‘ may be coded as
‗Y‘ or 1; ‗no‘ as ‗N‘ or 2 and ‗no response‘ or ‗unknown‘ as 'Ú' or 9.
o The codes should be entered on the questionnaires (or checklists) themselves.
o When finalising your questionnaire, for each question you should insert a box for the
code in the right margin of the page.
o These boxes should not be used by the interviewer. They are only filled in afterwards
during data processing.
o Take care that you have as many boxes as the number of digits in each code.
o If analysis is done by hand using data master sheets, it is useful to code your data as
well
o Coding conventions
o Common responses should have the same code in each question, as this minimizes
mistakes by coders.
o For example
Yes (or positive response) code – Y or 1
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
224
No (or negative response) code – N or 2
Don't know code – D or 8
No response/unknown code – U or 9
sample of (say 20) questionnaires.
o You may group similar types of responses into single categories, so as to limit their
number to at most 6 or 7.
o If there are too many categories it is difficult to analyse the data.
early in the study
STEP 4: Summarizing the Data in Data Master Sheets (30 Minutes)
Data master sheets
On a data master sheet all the answers of individual respondents are entered by hand. You
would need several sheets to include all answers.
Enter the different codes for one question in one column instead of having different
columns of which you tick one
No Education (Q3) Occupation (Q4)
Y/N Highest level Still in Self Head HH
school
Years Type
1 Y 4 PS N 1 3
2 Y 9 SS N 4 NA
3 N NA NA NA 5 NA
4 U PS Y 0 2
In any small-scale study processed by hand in which groups will be compared, a different
master sheet should be made for each of those groups, e.g., good and poor compliers to
treatment.
As gender is an important cross-cutting theme, it is usually also advisable to subdivide
males and females within each of the groups that are being compared
STEP 5: Compiling the Data Manually without Master Sheets (35 Minutes)
more efficient to do the compilation manually
o If only one person is doing the compilation use manual sorting.
o If a team of 2 persons work together use either manual sorting or tally counting.
___________________________________________________________________________

entered in a separate questionnaire.
o Take one question at a time, for example, ‗use of health facility‘,
o Sort the questionnaires into different piles representing the various responses to the
o Count the number in each pile.
o One member of the compiling team reads out the information while the other records
o Tally count for no more than two variables at one time (e.g., sex plus type of facility
used)
o After tally counting, add the tallies and record the number of subjects in each group.

etc., that describe the data.
o Frequency counts
From the data master sheets, simple tables can be made with frequency counts for
each variable.
A frequency count is an enumeration of how often a certain measurement or a
certain answer to a specific question occurs.
For example
Smokers 51
Non-smokers 93
Total 144
If numbers are large enough it is better to calculate the frequency distribution in
percentages (relative frequencies):

given. In other words, percentages standardize the data.
into categories. This process may include the following steps:
o Inspect all the figures: What is their range? (The range is the difference between the
largest and the smallest measurement.)
o Divide the range into three to five categories. You can either aim at having a
clinic distance) or you can define the categories in such a way that they are each equal
o Construct a table indicating how data are grouped and count the number of
observations in each group.
STEP 3: Using Figures to Present Data (10 minutes)
o Figures make the descriptive data more readable when you have many tables
o Numerical data
Histograms
Line graphs
Scatter diagrams
maps
o Categorical data
Bar charts
Pie charts
o Is simplest and most effective means of illustrating qualitative data
o Bars can either be horizontal or vertical
o Eg.57 Adolescents from Kaloleni streets in Arusha were asked the following question:
How often have you used cannabis for the past one year? This was closed question
with the following possible answers
o Frequently (more than 5 times), Occasionally ( 3 to 5 times), rarely (1 to 2
times)and never
Categories Number Percentage
Frequently 7 12.2
Occasionally 9 15.8

Pie charts
o Provides quick view of data presented in different form.
o Used in qualitative number with few categories to avoid congestion
Histograms
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
231
o Numerical data are often presented in histograms
o Which are similar to bar charts important difference is that in histogram ‗the bars‘ are
connected (as long as there is no gap between the data where as in bar charts are not
connected as the different categories are distinct entitles)
Line graphs
o Particularly useful for numerical data if you want to show Trend over time
o It is easy to show two or more distribution in one graph as long as difference between
lines are easy to distinguish e.g. age distribution between males and females
STEP 4: The Difference Between Mean, Mode and Median (30 minutes)
Activity: Small Group Discussion (20 minutes)
DIVIDE students into small manageable groups
ASK students to discuss on the following question
ALLOW students to discuss for 10 minutes
ALLOW few groups to present and the rest to add points not mentioned
CLARIFY and SUMMARIZE by using the contents below
o The mean of a data set is also known as the average value. It is calculated by dividing
the sum of all values in a data set by the number of values.
o So, in a data set of 1, 2, 2, 3, 4, 5, we would calculate the mean by adding the values
(1+2+2+3+4+5) and dividing by the total number of values (6). Our mean then is
17/5, which equals 3.4
o The mode is the most common observation of a data set, or the value in the data set
that occurs most frequently.
o The example of the mode in 1, 2, 2, 3, 4, 5, is 2
o The mode is an appropriate measure to use with categorical data
o The median of a data set is the value that is at the middle of a data set arranged from
smallest to largest.
o In the data set 1, 2, 3, 4, 5, the median is 3.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
232
o In a data set with an even number of observations, the median is calculated by
dividing the sum of the two middle values by two. So in: 1, 2, 2, 3, 4, 5, the median is
(2+3)/2, which equals 2.5.
o The median is appropriate to use with ordinal variables, and with interval variables
with a skewed distribution
STEP 5: Calculation of the Frequencies, Percentages, Proportion, Ratios,
Rates, Means, Medians, Modes for Major Variables (35 minutes)
Frequency distribution
o Frequency distribution is description of data presented in tabular form.
o Gives frequency in each value appears in data
o Count number of response in category
o E.g. Frequency of categorical nominal data
Distribution of course students according to sex
Sex course students Number of course students
Male 34
Female 27

Frequency distribution of numerical data
o Frequency distribution of numerical data is similar to that of categorical data except
here data have to be grouped in categories
school (45,43,45,47,54,53,62,38,54,34,45,53,56,42,51, 62,61)
o Procedures
Select group for grouping these data (selected Groups (31-40; 41-50; 51-60; 61-
70)
Count number of measurement (wt. of nurses) in each group:
31-40 II (34, 38)
41-50 IIIIII (42, 43, 45, 45, 45, 47)
51-60 IIIIII (51, 53, 53, 54, 54, 56)
61-70 III (61, 62, 62)
Add up and check totals.
o Groups must not overlap, to avoid confusion
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
233
o There must be continuity from one group to the other (no gaps)
o Groups must range from the lowest to the highest measurements
o Groups should normally be of equal width
o is number of units in the sample with a certain characteristics divided by total of units
in the sample multiplied by 100
o May also be called Relative frequencies
o Standardizes the data and make it easier to compare with similar data obtained in
another sample of different size or origin
Weight(Kg) Number of Pharmacy Relative frequency
students (percent)
31-40 12 26.7
41-50 17 37.8
51-60 11 24.4
61-70 5 11.1
Total 45 100
o Don‘t include missing numbers and not applicable in calculation.
o Don‘t know' is special category that should not counted as missing data.
o Should not be used if total is less than 30, as one unit makes a big difference in terms
of percentage
o Sometimes relative frequency are expressed in proportion instead of percentages
o Definition: proportion is numerical expression that compares one party of study units
to the whole.
o Can be expressed in fraction or decimal
Numerator is part of denominator
o It is numerical expression that indicates relationship in quantity or amount or size
between two or more parts.

exposure-condition association.
o To be a confounder
A risk factor must be associated with the risk factor under study.
It must also be a risk factor for the condition/problem being investigated.
A potential confounder is any factor that is believed to have a real effect on
the risk of the problem under study e.g. smoking, age, socioeconomic status and
education level
Types of Variables and scales
to carefully define the problem and each of the factors identified when analyzing
the problem
variable and independent variables (factors influencing the outcome or problem)
Numerical Variables
o When the values of the variables are expressed in numbers
Example of a variable in the form of numbers is person’s age. The
variable ‘age’ can take on different values since a person can be 20
years old, 35 years old and so on.
Weigh (expressed in kilograms or in pounds)
Homes-clinic distance (expressed in kilometers or in minutes
walking distance);
Monthly income (expressed in dollars, Shillings)
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
236
o Some variables may be expressed in categories. For example, the variable
sex has two
distinct categories, male and female.
Figure: Example of categorical variable
Variable Categories
Colour Red, blue, green, yellow
Main type of staple food Maize, rice, millet, cassava
Types of drugs Antibiotics, anti-inflammatory
o Continuous: With this type of data, one can develop more and more accurate
measurements depending on the instrument used. For example, height in
centimeters
(2.546 cm or 2.543216 cm) and Temperature in degrees Celsius (37.2 0 c or
37.190).
o Discrete: These are variables in which numbers can only take full values, e.g.
number of visits to a clinic (0, 1, 2, 3, and 4). Number of sexual partners (0, 1,
2, 3, 4,
and 5).
o Ordinal variables: These are grouped variables that are ordered or ranked in
increasing or decreasing order. For example:
High income (above $3000 per month), middle income ($1000-$3000 per
month), and low income (less than 1000 USD per months).
Disability: no disability, partial disability, serious or total disability.

PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
237
Seriousness of a disease: severe, moderate, mild.
Agreement with a statement: fully agree, partially agree, and fully
disagree.
o Nominal variables: The groups in these variables do not have an order or
ranking. For example
Sex: Male, female.
Main food crops: Maize, millet, rice.
Religion: Christian, Muslim, Hindu, Buddhism.
o Most of what we call factors are variables which have negative values.
o Contributing factors in negative phrase are such as lack of knowledge.
o Example:
Factor Variables
Long waiting time Waiting time
Absence of drugs Availability of drugs
Lack of supervision Frequency of supervision
o Quantitative variables:
Variables which have definitive quantitative values (age in years- 24 year
or 4 years or weight or height) and can be manipulated according to the
rules of mathematics.
Ordinal variables: Variables which do not have numerical values but can
be graded (e.g. level of education as primary school, advanced diploma
and bachelor’s degree or quality of services as poor, average, good).
Nominal qualitative variables or attributes (do not belong to either of the
above) examples are marital status-married, single, divorced or gender as
male or female.

must be
considered, either at planning stage or while doing data analysis.
For example:
o A relationship is shown between compliance with antimalaria treatment and
severe malaria in under-five children. However, mother’s education may be
related to compliance with the treatment and severe malaria.
o Mother’s education is a potential confounding variable. In order to give a true
picture

247
Data-collection techniques and tools used for the different study populations
Ethical consideration
o Chapter 4: Research findings
The systematic presentation of research findings in relation to the research objectives
is the crucial part of a report.
The description of findings should offer a good combination or triangulation of data
from qualitative and quantitative components of the study
There are two different ways in presentation of findings:
o As you listed all data by objective this should be easy.
o These integrated presentations will be a compilation of tables, graphs,
narrative interpretation and illustrative quotes from in-depth interviews or
FGDs
Presentation of data by research instrument
o Analyze the data by instrument and integrate the findings only in the
discussion.
o Separate analysis is indicated for objectives that are covered by distinct study
populations using specific instruments
o The list of data by objective will help you to decide how to organise the
presentation of data.
o When all data have been analysed, a detailed OUTLINE has to be made for
the presentation of the findings. This will help the decision-making on how to
organize the data
o Chapter 5: Discussion, the findings can now be discussed by
Objective or by cluster of related variables or themes,
The discussion should also include findings from other related studies that support or
contradict your own
o Chapter 6: Conclusions and Recommendations
They should follow logically from the discussion of the findings
Conclusions should be short
It should follow the sequence in which the findings have been presented.
The recommendations should be summarized according to the groups towards which
o References

STEP 4: Write Drafts of study Report in Stages (10 minutes)
o The cover page should contain the title, the names of the authors with their
titles and
positions, the institution that is publishing the report, (e.g. Pharmacy Council
of the MOH Tanzania), the month and year of publication.
o The title could consist of a challenging statement or question, followed by an
informative subtitle covering the content of the study and indicating the area
where the study was implemented.
o The summary should be written only after the first or even the second draft of
the report has been completed.
o It should contain:
A very brief description of the problem (why this study was needed)
The main objectives (what has been studied)
The place of study (where)
The type of study and methods used (how)
Major findings and conclusions, followed by
The major (or all) recommendations

part of your study that will be read.
whole.
o If you collaborated with various groups during the drafting and implementation
of the
research proposal, then consider writing different summaries for each of these
groups.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
249
o For example, you may prepare different summaries
For policy makers and health managers
For health staff of lower levels
For community members
For the public at large (newspaper, TV)
o In a later stage you may write articles in scientific journals
o Thank those who supported technically or financially in the design and
implementation of your study.
o Acknowledgements are usually placed right after the title page or at the end of
the report, before the references.
o A table of contents is essential
o It provides the reader a quick overview of the major sections of your report,
with page
references, so that she/he can go through the report in a different order or
skip certain
sections.
o If there are many tables or figures, then they may be listed in a table of
contents type of format with page numbers.
o If abbreviations or acronyms are used in the report, these should be stated in
full in the text the first time they are mentioned
o If there are many, then they should be listed in alphabetical order as well
o The list can be placed before the first chapter of the report.
o The table of contents and lists of tables, figures, abbreviations should be
prepared last
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
250
o A t this time include the page numbers of all chapters and sub-sections in the
table of
contents.
o Should contain relevant (environmental/ administrative/ economic/ social)
background data about the country, the health status of the population, and
health service data which are related to the problem that has been studied.
o The statement of the problem should follow
o Relevant literature collected during the implementation of the study.
o It should contain a paragraph on what you hope to achieve with the results of
the study.
o The general and specific objectives should be included as stated in the
proposal.
o If you have not been able to meet some of the objectives this should be stated
in the
methodology section and in the discussion of the findings.
o The objectives form the HEART of your study. They determined the
methodology you chose and will determine how you structure the reporting of
your findings.
o The methodology you followed for the collection of your data should be
described in
detail. This section should include a description of:
The study type;
Major study themes or variables (a more detailed list of variables on which
data was collected may be annexed);
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
251
The study population(s), sampling method(s) and the size of the
sample(s);
Data-collection techniques used for the different study populations; how
the data was collected and by whom;
Procedures used for data analysis, including statistical tests (if applicable)
o The systematic presentation of the findings in relation to the research
objectives is the
crucial part of your report.
o The description of findings should offer a good combination or triangulation of
data from qualitative and quantitative components of the study.
o Prepare an outline for the whole report, taking the main components of a
research report as a point of departure.
o An outline should contain:
The headings of the main sections of the report
The headings of subsections,
The points to be made in each section
A list of tables figures and/or quotes to illustrate each section
o Example of the outline of the chapter 4 on Research Findings

252
4.3.3 High prevalence of communicable diseases
4.3.4 Limited access to Reproductive and Child Health (RCH) and
weaknesses in RCH/nutrition services
o The system of numbering is flexible and can be extended according to need
with further headings or subheadings.
o The outline for the chapter on findings will predictably be the most elaborated.
o The first section under findings is usually a description of the study population.
o If different study populations have been studied, then provide a short
description of each group before presenting the data pertaining to these
informants.
o Depending on the study design, provide more information on the problem
studied (size, distribution, characteristics).
o In an analytic study, the degree to which different independent variables
influence the problem has be discussed.
o Tables and figures in the text need numbers and clear titles.
o Include only those tables and figures that present main findings and need
more elaborate discussion in the text.
o The first draft of your findings is never final.
o Therefore, you might concentrate primarily on content rather than on style.
o Nevertheless, it is advisable to structure the text from the beginning in
paragraph
.
o The findings can be discussed by objective or by cluster of related variables
or themes, which should lead to conclusions and possible recommendations.
o The discussion may include findings from other related studies that support or
contradict your own.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
253
o The conclusions and recommendations should follow logically from the
discussion of the findings.
o Conclusions can be short, as they have already been elaborately discussed in
chapter 5.
o As the discussion will follow the sequence in which the findings have been
presented
(which in turn depends on your objectives) the conclusions should logically
follow the
Specific objectives
o The recommendations may be summarized according to the groups towards
which they are directed, for example:
Policy-makers
Health and health-related managers at district or lower level
Health and health-related staff who could implement the activities
Potential clients
The community at large
o Remember that action-oriented groups are most interested in this section.
o In making recommendations, use not only the findings of the study, but also
supportive information from other sources.
o The recommendations should take into consideration the local characteristics
of the health system, constraints, feasibility and usefulness of the proposed
solutions.
o They should be discussed with all concerned before they are finalized.
o If the recommendations are short (roughly one page), include them all in the
summary
and omit them as a separate section in Chapter 6 in order to avoid repetition.
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
254
o The references in your text can be numbered in the sequence in which they
appear in the report and then listed in this order in the list of references
(Vancouver system).
o Another possibility is the Harvard system of listing in brackets the author’s
name(s) in the text followed by the date of the publication and page number,
for example:
o The annexes should contain any additional information needed to enable
professionals to follow your research procedures and data analysis.
o Information that would be useful to special categories of readers but is not of
interest to the average reader can be included in annexes.
o Examples of information that can be presented in annexes are:
Tables referred to in the text but not included in order to keep the report
short;
lists of hospitals, districts, villages etc. that participated in the study;
Questionnaires or check lists used for data collection.
o When a first draft of the findings, discussion and conclusions has been
completed, all
working group members should read it critically and make comments.
o The following questions should be kept in mind when reading the draft
Have all important findings been included?
Do the conclusions follow logically from the findings?
If some of the findings contradict each other, has this been discussed and
explained, if possible?
Have weaknesses in the methodology, if any, been revealed?
Are there any overlaps in the draft that have to be removed?
Is it possible to condense the content?
___________________________________________________________________________
PST 06210 Operational Research NTA Level 6 Semester 2 Facilitator Guide
255
In general, a text gains by shortening. Some parts less relevant for action may be
included in the annex Check if descriptive paragraphs may be shortened and
introduced or finished by a concluding sentence.
Do data in the text agree with data in the tables?
Are all tables consistent (with the same number of informants per
variable), are they numbered in sequence, and do they have clear titles
and headings?
Is the sequence of paragraphs and subsections logical and coherent?
Is there a smooth connection between successive paragraphs and
sections?
Is the phrasing of findings and conclusions precise and clear?
first
sentences of each paragraph. If this gives a clear impression of the organization
and
results of the study, then one may conclude that you did the best you could.
STEP 5: Checking the Final Draft for Completeness (10 minutes)
o The data are appropriate, trustworthy adequate for drawing inferences;
o The data reflect good homogeneity;
o Proper analysis has been done through statistical methods
o Weaknesses in logical development or presentation.
See whether the material, as it is presented, has unity and cohesion;
The researcher should give due attention to the fact that in his rough draft he has
been consistent or not.
The researcher should check the mechanics of writing—grammar, spelling and
usage
The report being written in a concise and objective style and in simple language,
Vague expressions has been the researcher has to avoid abstract terminology and
technical jargon
Checking whether the format has been followed
o When a first draft of the findings, discussion and conclusions has been completed, all
working group members and facilitators should read it critically and make comments.
