Chapter Objectives
Know the difference between primary and
secondary data and their sources.
Know the advantages and disadvantages of each
data collection method.
Make logical decisions as to the appropriate
data collection methods for specific study.
Be able to demonstrate your skills in
interviewing others, and to design
questionnaires.
2
Sources of Data
Primary data: information obtained firsthand by the
researcher on the variables of interest for the specific
purpose of the study.
3
Sources of Data
1. Primary sources: Refer to information
obtained firsthand by the researcher on the
variables of interest for the specific purpose
of the study. Examples of sources of Primary
data are individuals, focus groups, the
internet could also serve as a primary data
source when questionnaires are administered
over it.
4
Sources of Data
2. Secondary sources: Refer to
information gathered from sources
already existing from several sources.
As for example, company records,
government publications, industry
analyses offered by the media, web
sites, the internet, and so on.
5
Data collection Methods
Data collection Methods are an
integral part of research design. There
are several data collection methods,
each with its own advantages and
disadvantages.
6
Data collection Methods
Data collection methods include three
main methods:
1- Interviewing: It could be unstructured or
structured interviews.
2- Questionnaires
3- Other Methods of Data Collection

Interviewing
9
Unstructured Interviews
Unstructured Interviews are so labeled
because the interviewer does not enter the
interview setting with a planned sequence of
questions to be asked of the respondent.
The objective of the unstructured
interview is to bring some preliminary issues
to the surface so that the researcher can
determine what variables need further in-
depth investigation.
10
Structured Interviews
Structured Interviews are those conducted when
it is known at the outset what information is needed.
The interviewer has a list of predetermined
questions to be asked of the respondents either
personally, through the telephone or through the
medium of a PC.
The questions are likely to focus on factors that
had surfaced during the unstructured
interviews and are considered relevant to the
problem.
11
Interviewing
The Questioning Technique
Funneling
In the beginning of an unstructured interview, it
is advisable to ask open-ended questions to get
a broad idea and form some impressions about
the situation. For example a question that could
be asked, would be:
“what are some of your feelings about working for
this organization?”
12
Interviewing
The Questioning Technique
Unbiased Questions
It is important to ask questions in a way
that would ensure the least bias in the
response. For example:
“Tell me how you experience your job”
this question is better than,
“The work you do must be really boring;
let me hear how you experience it”
13
Interviewing
The Questioning Technique
Clarifying Issues
To make sure that the researcher understands issues as the
respondent intends to represent them, it is advisable to
restate or rephrase important information given by the
respondent. For example, if the interviewee says,
“There is an unfair promotion policy in this organization;
seniority does not count at all. It is the juniors who always
get promoted”.
The researcher might interject and ask,
“So you are saying that juniors always get promoted over
the heads of even capable seniors.”

Interviewing
The Questioning Technique
Helping the Respondent to Think Through Issues.
15
Interviewing
The Questioning Technique
Taking Notes
when conducting interviews, it is important that
the researcher makes written notes as the
interviews are taking place, or as soon as the
interview is terminated. The interviewer should
not rely on memory. Information based solely on
recall introduces bias into the research.
The interviews can be recorded on tape if the
respondent has no objections.
16
Personal Interview
Advantages
Can clarify doubts about questionnaire
Can pick up non-verbal cues
Relatively high response/cooperation
Special visual aids and scoring devises can be used
Disadvantages
High costs and time intensive
Geographical limitations
Response bias / Confidentiality difficult to be assured
Some respondents are unwilling to talk to strangers
Trained interviewers
17
Telephone Interview
Advantages
Discomfort of face to face is avoided
Faster / Number of calls per day could be high
Lower cost
Disadvantages
Interview length must be limited
Low response rate
No facial expressions

Questionnaire Design
Definition
A questionnaire is a pre-formulated, written set of
questions to which the respondent records his answers
Steps
1. Determine the content of the questionnaire
2. Determine the form of response
3. Determine the wording of the questions
4. Determine the question sequence
5. Write cover letter

Guidelines for Questionnaire
Design
Classification Data or Personal
Information.
It is a wise policy to ask for the
personal information by providing a
range of response options, rather than
asking exact figures. For example, the
variables can be tapped as shown
below:
26
Guidelines for Questionnaire
Design
Example 1
Age (years) Annual Income
Under 20 □ Less than $20,000
20 – 30 □ $20,000-30,000
31 – 40 □ $30,001-40,000
41 – 50 □ $40,001-50,000
51 – 60 □ $50,001-70,000
Over 60 □ $ Over 70,000
27
Principles of Measurement
There are some principles of
measurement to be followed to ensure that
the data collected are appropriate to test our
hypotheses.
These refer to the scales and scaling
techniques used in measuring concepts, as
well as the assessment of reliability and
validity or the measures used, which were
all discussed before.
28
Principles of Measurement
Appropriate scales have to be used depending on
the type of data that need to be obtained.
Wherever possible, the interval and ratio scales
should be used in preference to nominal or ordinal
scales.
Once data are obtained, the “goodness of data” is
assessed through tests of validity and reliability.
Validity establishes how well a technique,
instrument, or process measures a particular
concept, and reliability indicates how stably and
consistently the instrument taps the variable.

General Appearance of the
Questionnaire
Example 3
The president of Mideast Co. suspects that
most of the 500 male and female employees
of the organization are somewhat alienated
from work.
He is also of the view that those who are
more involved (less alienated) are also the
ones who experience greater satisfaction with
their work lives.
Design a questionnaire the president
could use to test his hypothesis.
38
General Appearance of the Questionnaire:

Data collection Methods: Other
Methods of Data Collection
Observational Surveys.
It is possible to gather data without asking questions
of respondents. People can be observed in their
natural work environment or in the lab setting, and
their activities and behaviors can be noted and
recorded.
52
Structured Observations
Different types
Personal observation
Electronic observation
53
Observational Surveys
54
Nonparticipant-Observer
The researcher may collect the needed data
without becoming an integral part of the
organizational system.
For example, the researcher might sit in the
corner of an office and watch and record how
the manager spends his time.
Observation of all the activities of managers,
over a period of several days, will allow the
researcher to make some generalizations on
how managers spend their time.
55
Participant-Observer
The researcher may play the role of the
participant-observer. The researcher
enters the organization or the research
setting, and becomes a part of the work
team.
For instance, if a researcher wants to study
group dynamics in work organization, then he
may join the organization as an employee
and observe the dynamics in groups while
being a part of the work groups.
56
Structured Versus Unstructured
Observational Studies
57
Structured Versus Unstructured
Observational Studies
Structured Observational Studies
The observer has a predetermined
set of categories of activities or
phenomena planned to be studied.
People can be observed in their
natural work environment and their
normal activities and behaviors, and can
be noted and recorded.
58
Structured Versus Unstructured
Observational Studies
Unstructured Observational
Studies
If the observer has no definite ideas of
the particular aspects that need focus,
he could record everything that is
observed.
59
Mechanical Observation
61
Disadvantages of Observational
Studies
1. It is necessary for the observer to be
physically present over a long period of time
(unless a camera or another mechanical
system can capture the events of interest).
2. It is slow, tedious, and expensive.
62
Advantages and Disadvantages of
Summary of Observational Studies
63
Mulimethods of Data Collection
64
Ethics and the Researcher
Several ethical issues should be
addressed while collecting data. These
pertain to:
those who sponsor the research
those who collect the data
and those who offer them.
65
Ethics and the Sponsors
1. The sponsors should ask for the study to be done
to better the purpose of the organization, and not
for any other self-serving reason.
2. They should respect the confidentiality of the data
obtained by the researcher, and not ask for the
individual or group responses to be disclosed to
them, or ask to see the questionnaires.
3. They should have an open mind in accepting the
results and recommendations in the report
presented by the researcher.
66
Ethics and the Researcher
1. Treating the information given by the
respondent as strictly confidential and
guarding his privacy is one of the primary
responsibilities of the researcher.
2. The researcher should not misrepresent the
nature of the study to subjects, especially in
lab experiments. The purpose of the
research must be explained to them.
67
Ethics and the Researcher
3. Personal information should not be solicited,
and if it is absolutely necessary for the
project, it should be tapped with high
sensitivity to the respondent, offering
specific reasons therefore.
4. Whatever be the nature of data collection
method, the self-esteem and self-respect of
the subjects should never be violated.
68
Ethics and the Researcher
5. No one should be forced to respond to the
survey .
6. Nonparticipant-observers should be as
nonintrusive as possible. His personal
values could easily bias the data.
7. Subjects should never be exposed to
situations where they could be subject to
physical or mental harm.
8. There should be absolutely no
misrepresentation or distortion in reporting
the data collected during the study.
69
Ethical Behavior of the Respondents
1. The subject, once having exercised the
choice to participate in a study, should
cooperate fully in the tasks ahead, such as
responding to a survey or taking part in an
experiment.
2. The respondent also has an obligation to be
truthful and honest in the responses.
Misrepresentation or giving information,
knowing it to be untrue, should be avoided.
