Questionnaire
Design
What is a
Questionnaire?
A set of Questions
designed to generate
the information
needed to accomplish
the research objectives
Purposes of the Questionnaire
Ensures standardization and comparability of the data
across interviews – everyone is asked the same questions
Increases speed and accuracy of recording
Facilitates data processing
Allows the researcher to collect the relevant information
necessary to address the management decision problem
Improper design can lead to?
Incomplete information
Inaccurate data
Higher costs
Criteria to consider
 Does it provide the necessary
information
 Does it consider the respondent
 Does it meet editing, coding and
data processing requirements
Designing the Questionnaire
Logical Steps to Develop a Good Questionnaire
 Determine survey objectives: Plan what to measure.
 Decide on format. E.g. personal interview, telephone, self.
 Formulate questions to obtain the needed information
 Decide on the wording of questions
 Decide on the order and layout of the questionnaire
 Using a sample, test the questionnaire for omissions and
ambiguity
 Correct the problems (pretest again, if necessary)
The Major Decisions in
Questionnaire Design
1. Content - What should be asked?
2. Wording - How should each question be phrased?
3. Sequence - In what order should the questions be
presented?
4. Layout - What layout will best serve the research
objectives?
The most difficult step is specifying exactly what
information is to be collected from each respondent
Content: Questions must meet 5
requirements
1. Are the questions relevant. Do they pertain to the
research problem
2. Are the questions accurate. Do they accurately depict the
attitudes, behaviors, etc. intended to investigate
3. Do respondents have the necessary information?
• Qualify respondents
4. Do respondents understand and interpret the question
correctly
5. Will respondents give the information?
How should the questions be asked?
Format: How much freedom do we give respondents in
answering questions
Open-ended questions
– What do you look for most in a job?
– Is there anything else you would like to add about the product
Open Ended Questions: key advantages
 Wide range of responses and information can be
obtained
Answers based on respondent’s not researcher’s frame
of reference – consumer’s terms (helpful in marketing
campaigns)
 Lack of influence. Don't channel respondents thinking
 Can help interpret closed-ended questions - why
 Particularly useful as introduction to survey or topic
 When it’s important to measure the salience of an issue
 When too many possible responses to be listed or
unknown
Open-ended questions: Key disadvantages
Ability and/or willingness of respondent to answer
 Interviewer’s ability to record answers quickly or summarize
accurately & probe effectively
 Interviewer’s attitude influences response
 Time consuming (interview sessions, tabulation,
classification, assignment, validation)
 Difficulty in coding
 Require respondents to be articulate
 Respondents may miss important points
 Non-response
Closed-ended questions (Fixed-alternative responses)
What do you look for most in a job?
____ Work that pays well
____ Work that gives a sense of accomplishment
____ Work where you make most decisions by yourself
____ Work that is steady with little chance of being laid off.
Advantages
 Ease of understanding
 Requires less effort on part of interviewer and respondent
 Ease of tabulation & analysis
 Less error prone
 Less interviewer bias
Less time consuming
 Answers directly comparable from respondent to respondent
Closed-ended questions (Fixed-alternative questions)
Disadvantages
 Middle/Neutral categories often selected inappropriately
(ignorance, safety)
 Less opportunity for self-expression or subtle qualifications
 Less involving for respondents
 Order of response categories can have major impact on results
Key tradeoff
 Want to get respondent to address issues our research is
concerned with (Forced response) and at same time give
respondent opportunity to honestly opt out of question (i.e.,
Don’t Know, No Answer, Neither Agree nor Disagree) so as not to
dilute data collected
Dichotomous Questions
Should the Alberta Government give consumers an energy rebate?
1. Agree
2. Disagree
Advantages
 Easy to administer and tabulate
Disadvantages
 Prone to large amounts of error since polarized reposnses
prevent gaining information on the range of variation
 Fail to communicate any intensity of feeling
Multiple Choice Questions
Are all possible alternatives included?
Too many alternatives
Position Bias
Scaled Response Questions
 Closed ended questions where the response choices are
designed to capture an intensity of feeling
Easy to code and more powerful statistical tools
Main problem: Respondent misunderstanding
Question Wording
Can have major impact on how respondent interprets question
All respondents should interpret in the same way
Things to avoid
 Complexity: use simple, direct, conversational language
leading questions -- that suggest or imply certain answers
loaded questions -- suggest social desirability, or are emotionally
charged. Have you purchased a high quality Sony TV this year
Ambiguity and vagueness: Words such as “often”, “occasionally”,
“usually”, “regularly”, “frequently”, “many”, should be used with
caution. If these words have to be used, their meaning should be
explained properly.
Which province is bigger Manitoba or Alberta? – would your
answer be based on population or area?
More things to avoid
long-worded questions
 double-barreled items. Questions that refer to two or
more issues within the same question. Where respondent
may agree with only 1 part of multipart statement.
 Do you think Nike offers better pricing and variety
than other brands
 Making implicit assumptions
Jargon
More things to avoid
 burdensome questions - that may tax the respondent’s
memory
 How many tubes of toothpaste have you purchased
in the last 3 months
 Have you purchased toothpaste in the past week
Embarrassing, sensitive, or threatening questions:
 Have you charged more on your credit card than
you should
 Use third person do you think most people…..
Surveys are more than a collection of unambiguous
questions
How questions are specified and put together will influence
the respondents’ willingness to participate & the responses
they provide
Sequence & Layout Decisions
Initial stages
 Screening or qualifying Questions: Have you been to the cinema
this month?
 Need to gain & maintain respondent’s cooperation
 Make questionnaire simple for interviewer to administer
opening questions should be interesting, simple, and easy to
answer.
 which theatre did you go to last?
Transition Questions
 What aspects of the theatre did you like best
Questions directly related to research objectives which
require more effort and get respondent thinking about topic
Difficult and Complicated Questions
 The following 10 questions relate to the characteristics of
theatres
Respondent now committed and can see an end in sight
Classifying and Demographic Questions
 What is your average annual household income
May not be answered (sensitive or threatening) but most
questions have been answered
Other Considerations
General questions should be asked before more specific ones
 Demographic questions should come at the end.
 Use multiple questions instead of one
 Similar questions together
– consistent mindset for respondents
 Develop a logical flow
 Use transitions between sections (E.g. In this section we ask
questions about X)
Distinguish between instructions, questions and responses
CAPS or BOLD or Underline versus lower case or
unformatted
Distinguishing question and responses:
INSTRUCTIONS LAYOUT A:
Do you agree, disagree or have no opinion that this company has:
• A good vacation policy - disagree/not sure/agree.
• Good management feedback - disagree/not sure/agree.
• Good medical insurance - disagree/not sure/agree.
INSTRUCTIONS LAYOUT B:
Does this company have:
___
• A good vacation policy
Disagree Not Sure Agree
1
2
3
• Good management feedback 1

• Good medical insurance

–Filter and pivot questions should be used as
necessary.
– A FILTER question is one that screens out
respondents who are not qualified to answer a
second question.
–A PIVOT question is a type of filter question that
is used to determine what version of a second
question to ask.
Developing a logical flow
 If the questionnaire deals with several topics,
complete questions on a single topic before moving
on to a new topic
 If topics are related, ask questions on related topics
before asking questions about unrelated topics
 If you ask questions about behaviors over some time
period, follow chronological order backward in time
 When changing topics, use some transitional phrase
QUESTIONNAIRE LAYOUT
The layout and physical attractiveness of a
questionnaire are important aspects
 Questionnaires should be designed to appear as
short as possible
 Questionnaires should not appear overcrowded
Leave lots of space for open ended questions
 Questionnaires in booklet form are often
recommended
OPENING
Provide first name (at least)
Provide name of company doing research
Provide reason for survey and topic
State that no selling will be involved and no personal data
other than for statistical purposes
Tell respondent approximate time to complete
Reinforce that respondent’s time is appreciated
Invite to participate
AND CLOSING
Thank for time
Ask if they had a positive experience and remind them that
their opinions count
Pretesting and Correcting Problems
Purpose of pretest: To ensure that the questionnaire meets the
expectations in terms of the information that will be obtained
Is question necessary – does it serve a purpose, will info be used
Missing important variables – does it provide the info needed
Match questions to objectives
Pretest Specific Questions For
• Variation
• Meaning
• Task difficulty
• Respondent interest and attention
• Ambiguous, ill-defined, loaded, double-barreled questions
Pretest the Questionnaire
• Flow of the questionnaire
• Skip patterns
•Length
Respondent Interest and Attention
