Data Collection Methods
CHAPTER 10
1
Know the difference between primary and secondary data and their sources.
Know the advantages and disadvantages of each method.
Make logical decisions as to the appropriate data collection methods for specific study.
Demonstrate your skills in interviewing others to collect data.
2
Chapter Objectives
Design questionnaires to tap different variables.
Evaluate questionnaires, distinguishing the “good” and “bad” questions therein.
Apply what you have learned to class assignments and projects.
3
Chapter Objectives
There are two 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
Sources of Data
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
7
Data collection Methods
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.
8
Unstructured 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.
9
Structured Interviews
The unstructured and structured interviews have several forms:
Interviews Face-to-face Telephone interviews Electronic media interviews
10
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?”
11
Interviewing
The Questioning TechniqueUnbiased 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”
12
Interviewing
The Questioning TechniqueClarifying 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.”
13
I
The Questioning Technique
Helping the Respondent to Think Through Issues.
If the respondent is not able to verbalize his perceptions, or replies, “I don’t know,” the researcher should ask the question in a simpler way or rephrase it. For example, the respondent might be asked which task he would prefer to do: serve a customer or do some filing work. If the answer is “serve the customer,” the researcher might use another aspect of the respondent’s job and ask the paired-choice question again. The respondent can sort out which aspects of the job he likes better than others.
14
Interviewing
The Questioning TechniqueTaking 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.

Questionnaire Administration
23
Guidelines for Questionnaire Design
Ambiguously worded and respondent may not be sure what exactly they mean.
◦ To what extent would you say you are happy.
24
Ambiguous Questions
Requires respondent to recall experience or event from the past that are hazy in their memory.◦ When you started working in this department,
environment was not good.
25
Recall Dependent
Emotionally charged questions.
Domestic Violence Have you stopped beating your wife? How much you think these qualities lack in
you.
26
Loaded Questions
That lead the respondent to give the response s that the researcher would like or want them to give.◦ Don’t you think that in these days of escalating
costs of living , employees should be given good pay raises? BETTER
To what extent do you agree that employees should be given higher pay raises?
27
Leading Questions
Double Barreled Questions A question that lends itself to different
possible responses to its subparts .Two or more separate questions should be asked.◦ Do you think there is a good market for the
product and that it will sell well.
28
Socially desirabilityIncludes socially desirable response.
Do you think that older people should be laid off?
29
Positively and Negatively Worded QuestionsIt is advisable to include some negatively
worded questions as well .q.1 I feel I have been able to accomplish a
number of different things in my job. q.2 I do not feel I am very effective in my job.

31
Guidelines for Questionnaire Design
32
Guidelines for Questionnaire Design
Classification Data or Personal Information.
Personal information elicit such information as age, educational level, marital status, and income.
Unless absolutely necessary, it is best not to ask for the name of the respondent.
It is a matter of choice for the researcher to let the personal information appears in the beginning or at the end of the questionnaire.
33
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:
34
Guidelines for Questionnaire Design
Example 10.1 Age (years) Annual Income
Under 20 □ Less than $20,00020 – 30 □ $20,000-30,00031 – 40 □ $30,001-40,00041 – 50 □ $40,001-50,00051 – 60 □ $50,001-70,000Over 60 □ $ Over 70,000
35
Guidelines for Questionnaire Design
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.
36
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.
37
Principles of Measurement
It is necessary to pay attention to how the questionnaire looks. An attractive and neat questionnaire have the following elements:A good introductionOrganizing questions Giving instructions and guidanceGood alignmentThese elements are briefly discussed with
examples.
38
General Appearance of the Questionnaire
Exercise 1 A production manager wants to assess the
reactions of the blue-collar workers in his department to the introduction of computer-integrated manufacturing (CIM) systems. He is particularly interested to know how they would perceive the effects of CIM on:
a. their future jobs b. additional training that they will have to
receive c. future job advancement. Design a questionnaire for the production
manager.

The opportunities for training 1 2 3 4 5 will have to be enhanced with CIM.
42
General Appearance of the Questionnaire
4. I am not sure if CIM will need 1 2 3 4 5 all the people we now have in this department.5. I feel that most of us may not 1 2 3 4 5 have better opportunities for future promotions in the new manufacturing environment.6. Most of us will need special 1 2 3 4 5 training to work with CIM.7. I am sure the future looks bright 1 2 3 4 5 for most of us here.
43
General Appearance of the Questionnaire
Items 4 and 7 measure opinion about their future jobs.
1, 3, and 6 measure perceived training needs.
2, and 5 measure job advancement.
44
General Appearance of the Questionnaire
Exercise 2 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.
45
General Appearance of the Questionnaire
Before we can design a questionnaire, we need to list the variables to be tapped and operationally define the more abstract concepts. The following variables are mentioned in the study:
1. Involvement (or the other end, alienation). 2. Satisfaction with work life.
46
General Appearance of the Questionnaire: Exercise 2
The following demographic variables might be of interest to the study:
3. Gender 4. Tenure (number of years in the organization) 5. Job level 6. Age 7. Education These demographic variables help to describe the
sample, also, they might have an influence on the involvement (or alienation) of the employees, their level of satisfaction, and the relationship between the two.
47
General Appearance of the Questionnaire: Exercise 2
Operational Definition of Involvement would include the dimensions of the job being of central interest to individuals, and the major happiness being derived from the job. Low involvement can be considered as alienation.
Items that measure involvement are: 1. The major happiness of my life is derived from my job.
2. Time at work flies by quickly. 3. Working here is boring. 4. Nothing in life is as important as work. 5. I live, eat, and breathe my job. 6. My work helps me establish who I am.
48
General Appearance of the Questionnaire: Exercise 2
Operational Definition of Satisfaction would include dimensions of satisfactions with various aspects of the work environment such as with pay, supervision, promotion, and the like.
Questions that describe satisfaction at work place are:
To what extent would you agree with the following statements?
1. My work is fascinating.2. My work gives me a sense of
accomplishment.3. My supervisor praises good work.
49
General Appearance of the Questionnaire: Exercise 2

3- 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.
People movements, work habits, their facial expressions of joy, anger, and other emotions , and body language can be observed.
59
Data collection Methods: Other Methods of Data Collection
The researcher can play one of two roles while gathering field observational data:Nonparticipant-ObserverParticipant-Observer
60
Observational Surveys
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.
61
Nonparticipant-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.
62
Participant-Observer
Structured Observational Studies Both the nonparticipant-observer and
participant-observer could be either structured or unstructured.
63
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.
64
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.
65
Structured Versus Unstructured Observational Studies
Machines can provide data by recording the events of interest as they occur, without a researcher being physically present. Films and electronic recording devices such as video cameras can be used to record data. Such mechanically observed data are error-free.
66
Mechanical Observation
1. The data are more reliable and free from respondent bias.
2. It is easier to note the effects of environmental influences on specific outcomes.
3. It is easier to observe certain groups of individuals whom are unable to give information
( like small children).4. It captures the attitudes, facial expressions and
other nonverbal behaviors, but cannot capture the thought of the individuals.
5. Observer have to be trained in what and how to observe, and ways to avoid observer bias.
67
Advantages 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.
68
Disadvantages of Observational Studies

Mulimethods of Data Collection
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.
71
Ethics and the Researcher
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.
72
Ethics and the Sponsors
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.
73
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.
74
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.
75
Ethics and the Researcher
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.
76
Ethical Behavior of the Respondents
Comment on each of the following questions stating whether they are good or bad and the reasons for your answer. Do not worry about their scaling.
1. If you have been in the company for over 15 years, please indicate the date of your joining this company.
2. My boss is good but excitable in his dealing with others.
3. Working women should opt not to have children.
77
Practice Exercise on Good and BadQuestions
4. Investment in children’s future should be an important goal of the administration.
5. This job uses a lot of the skills that I possess.
6. If this country is to remain competitive, should we not be spending more on research?
78
Practice Exercise on Good and BadQuestions
1. Bad question: recall dependent.2. Bad: Double-barreled.3. Bad: Loaded question; an emotional issue
for women.4. Bad: Social desirability.5. Good question. No problem with wording.6. Bad question: Leading question.
