Quality aims in survey
research
•
•
•
•
Goal is to collect information that is:
Valid: measures the quantity or concept that is supposed to
be measured
Reliable: measures the quantity or concept in a consistent
or reproducible manner
Unbiased: measures the quantity or concept in a way that
does not systematically under- or overestimate the true
value
Discriminating: can distinguish adequately between
respondents for whom the underlying level of the quantity or
concept is different

Steps to design a
questionnaire:
1.
2.
3.
4.
5.
6.
Write out the primary and secondary aims of your
study.
Write out concepts/information to be collected
that relates to these aims.
Review the current literature to identify already
validated questionnaires that measure your
specific area of interest.
Compose a draft of your questionnaire.
Revise the draft.
Assemble the final questionnaire.
4. Questionnaire
•
•
The use of questionnaires is an indirect
method of research used to gather a
wide-range of information from a large
population.
Questionnaires are designed so that the
participant must read the questions that
they are being asked and must then
answer them based on the response
style.
5. Types of Questions
•
–
•
•
–
Contingency – A question that only applies to
people who responded in a certain way to
another question
If yes complete this section if no, move to next
section
Matrix - A series of questions that’s share
answer choices
Scaled - Responses are graded on a
continuum
How important do you think standardized test
scores are to a fifth grader’s
6. Type of Questions
•
–
•
–
–
Open Ended – Questions that the
respondent can write their own answer.
Unstructured – Randomly Generated
Questions
What do you like to do on your spare time?
Word Association – Participant chooses the
first word that comes to mind based on the
list of words presented.
Completion – Finish a story, sentence or
picture that has already been started.
7. Types of Questions
•
–
•
–
•
–
–
–
–
Closed Ended – Questions with a list of options to
choose from.
Dichotomous – Questions with two possible responses
(Yes or No) or (True or False)
Do you know your weight ?
Multiple Choice – Questions with several options to
choose from
Why don’t you use the school ‘s cafeteria services?
It’s too expensive
Severing times conflict with my class schedule
The location is inconvenient
The food quality is poor
8. Subjective vs. Objective
•
–
•
–
Objective data are questions that are not
influenced by personal preferences and
beliefs.
Are you an MIS major?
Subjective data are questions that are
heavily influenced on personal
preferences and beliefs.
Do you like BA 3810?
9. Qualitative vs.
Quantitative
•
•
•
Quantitative data is numerical based data
that is counted then analyzed
Qualitative data is more precise data that
contains words, pictures or objects.
In the majority of research, qualitative data
is preferred and has shown to provide more
accurate answers than quantitative data.
10. Questionnaire Tips
•
•
•
•
•
Clarity – Try to make the questions as clear as
possible and not heavily based upon
interpretation
Wording of Questions – It is important to
create questions that will give you the most
precise answer that you want
Avoid similar responses choices
Do not include questions that will provide data
that isn’t related to your goals & objective
Add Open-Ended questions so that interested
participants can further express their opinions
12. Questionnaire Positives
•
•
•
It is a cost and time efficient way of
collecting a variety of data from large
populations
Less pressure on the respondent to
respond quickly or in a certain way
They are easy to analyze and record the
data
13. Questionnaire Negatives
•
•
•
•
Sampling Error – The margin of error
Response Bias – The respondents
answer’s are not their true beliefs
Non-response Bias – Those who
participate in a survey answer differently
that those who don’t.
Wording of Question – Sometimes the
question is misunderstood because of
wording.
14. Interview
•
•
•
An interview is a direct method of research
used to gather information for a specific
purpose.
In interviews, the interviewer has the capability
to learn more about how participants feel about
the questions based on their body movements.
The interviewer can also clarify any
misinterpretations of certain questions so that
the answers will be more accurate.
15. Interview Format
•
•
•
Structured – An organized interview with a
specific list of questions and no
interruptions from the interviewer.
Cognitive – Involves a series of methods
used to figure out the process the
participant goes through in a specific
situation.
Unstructured – A free-flowing interview
with little organization and fewer
questions.
16. Interview Type
•
•
•
Personal – Interviewer and Interviewee
are going through interview face-to-face
Telephone – Conducting an interview via
telephone
Web Interview – Interviewing with e-mail,
chat room or other form of
communication over the web.
17. Interview Tips
•
•
•
•
Clarity – Speak clearly and properly so that the
participant can understand you.
Have a set list of questions that you would like
to ask the participant and interact with them if
necessary.
Try to clock how long the interview will take so
you don’t go overboard and run out of time.
Try not to offend or throw off the participant
with your questions and body motions.
18. Interview Positives
•
•
•
•
Responses are typically more detailed
Interviewer can explain questions that
are unclear
Interviewer can observe the participants
body language
The Interviewer can add additional
questions if they feel that the
information will help their research.
19. Interview Negatives
•
•
•
It can be difficult to get all the samples that you
would like to because of high cost and amount
of time needed.
Courtesy Bias – the tendency for respondents to
give answer that they think the interview wants
to hear, rather than what they really feel
Faulty memory – some respondents may answer
a question incorrectly simply because of a poor
memory
20. Ch 11 20
What is a Questionnaire?
• A questionnaire is the vehicle used to
pose the questions that the
researcher wants respondents to
answer.
21. Ch 11 21
Questionnaire Design
• Questionnaire design is a systematic
process in which the researcher
contemplates various question
formats, considers a number of
factors characterizing the survey at
hand, ultimately words the various
questions very carefully, and
organizes the questionnaire’s layout.
22. Ch 11 22
The Functions of a
Questionnaire
•
•
•
•
Translates the research objectives
into specific questions
Standardizes those questions and
the response categories
Fosters cooperation and motivation
Serves as permanent records of the
research
23. Ch 11 23
The Functions of a
Questionnaire
•
•
Can speed up the process of data
analysis
Can serve as the basis for reliability
and validity measures

Steps in the Questionnaire
Development Process (Figure
11.1)
25. Ch 11 25
Developing Questions
• Question development is the practice
of selecting appropriate response
formats and wording questions so
that they are understandable,
unambiguous, and unbiased.
27. Ch 11 27
How wording affects answers
Did you see…
A broken headlight?
The broken headlight?
Which generates
more agreement?

Words to Avoid in
Questionnaire Development
•
•
•
•
•
•
•
All
Always
Any
Anybody
Ever
Every
Never
29. Ch 11 29
Why Avoid These Words?
•
•
–
–
These words: all, any, anybody, best,
ever, every, never, etc. are all EXTREME
ABSOLUTES…
They place respondents in a situation
where they must either fully agree or
they must completely disagree with the
extreme position in the question.
Do you always observe traffic signs?
Would you say all cats have four legs?
30. Ch 11 30
Four “Do’s” of Questionnaire
Wording
• Question evaluation refers to
scrutinizing the wording of a
question to ensure the question is
not biased and is worded such that
respondents understand it and can
respond to it with relative ease.
31. Ch 11 31
Four “Do’s” of Questionnaire
Wording
1.
2.
3.
4.
The question should be focused on a
single issue or topic. “What type of
hotel do you stay in on a trip?”
Pleasure or business trip? En route or
final destination?
The question should be brief.
The question should be
grammatically simple, if possible.
The question should be crystal clear.
32. Ch 11 32
Four “Do Not’s” of
Questionnaire Wording
1.
2.
The question should not “lead” the
respondent to a particular answer.
“Don’t you see any problem with
using credit cards for online
purchases?”
The question should not have
“loaded” wording or phrasing. Use
universal beliefs…Since our Founding
Fathers gave us the right to bear
arms…
33. Ch 11 33
Four “Do Not’s” of
Questionnaire Wording
3.
4.
The question should not be “double-
barreled.”
The question should not use words
that overstate the condition…do not
use “dramatics.” “Would you buy
sunglasses that protect your eyes
from harmful ultraviolent rays that
cause blindness?”
34. Ch 11 34
What is wrong with each
question?
How do you feel about Sears?
When some gasoline or electric-powered
product in your house breaks, do you call the
Sears repair service?
If the Sears repair service schedule was not
convenient for you, would you consider or not
consider calling a competing repair
organization to fix the problem you have?
How much do you think you would have to pay
to have Sears fix something that needs to be
repaired?
Shouldn’t concerned parents use car seats?
Should car seats be used for our loved ones?
Do good parents and responsible citizens use
car seats?
Do you believe infant car seats can protect
riders from being maimed?

Questionnaire Organization
•
•
Questionnaire organization is the
sequence of statements and
questions that make up the
questionnaire.
It is important because the
questionnaire appearance and ease
of flow affect the quality of the
information gathered.
38. Ch 11 38
Questionnaire Organization
• The introduction is called a “cover
letter” if the introduction is written to
accompany a mail survey or online
survey.
39. Ch 11 39
Questionnaire Organization
•
–
–
–
–
–
Five functions:
Identifies the surveyor/sponsor
Indicates the purpose of the survey
Explains how the respondent was
selected
Requests for/provides incentive for
participation
Determines if respondent is
suitable
41. Ch 11 41
Incentives
• Incentives are offers to do something
for the respondent to increase the
probability that the respondent will
participate in the survey.
42. Ch 11 42
Incentives
•
–
–
–
Incentives may be monetary or non-
monetary.
Anonymity: respondent assured
name not identified
Confidentiality: respondent’s name
is known by the researcher but not
divulged to a third party
Both are used as non-monetary
incentives to increase participation
43. Ch 11 43
Screening Questions
•
•
Screening questions are used to
ferret out respondents who do not
meet research study qualifications.
Research objectives should specify
who should and should not be
included in the research study.
44. Ch 11 44
Screening Questions
•
•
•
Example: If you were conducting
research on factors consumers use in
selecting a new car, wouldn’t you only
want to talk to persons who have
recently selected a new car?
If you were doing a study to determine
the potential for an e-zine targeting
college students, wouldn’t you only
want to talk to college students?
Screening or qualifying questions are
asked to ensure you are talking to your
target population.

Coding the Questionnaire
•
•
–
–
Coding: use of numbers associated
with question responses
Numbers are preferred for two
reasons:
Numbers are easier and faster to
keystroke into a computer file.
Computer tabulation programs are
more efficient when they process
numbers.
54. Ch 11 54
Performing the Pretest of the
Questionnaire
•
•
A pretest involves conducting a dry
run of the survey on a small,
representative set of respondents in
order to reveal questionnaire errors
before the survey is launched.
It is important to pretest on
respondents that are representative
of the target population to be studied.

57. 3. When to use an online questionnaire?
•
•
•
–
Internet offers great methodological potential
and versatility
Resulted in proliferation in online
questionnaires
But use of online questionnaire must be
appropriate and justified for each particular
research project
e.g. to address aims of research, selection of most
relevant questionnaire type and question format for
addressing aims, establishing a justified sampling strategy
to recruit relevant respondents and ensure appropriate
response rate
