5.7 Summary
Designing a questionnaire is clearly a crucial part of the market research process.
Questionnaires are used in different types of survey, from the highly structured
commonly used in-street and postal surveys to the informal, where interviewers may
ask open questions requiring in-depth answers. Whatever the purpose of the survey,
the main aims of the questionnaire are to:
obtain accurate information from the respondent
provide a structure and format to an interview
facilitate data analysis.
The chapter has demonstrated important considerations to be remembered when
framing questions and laying out the questionnaire. Of particular importance in
asking questions is the need to be clear and simple and to avoid bias which occurs
when questions are leading, hypothetical or ambiguous.
It should also be stressed that the testing of questions within pilot surveys is critical.
This will show up problems of understanding and misinterpretation and give some
indications of the likely results. On this latter point, it should be borne in mind that it
is possible (and probable) that you will achieve different results when asking the
same question but using open rather than closed techniques. For example, an open
question asking ‘What did you like about your last holiday?’ would probably provide
a wide range of answers which reflected that respondent’s own particular
circumstances and experiences. If, however, the question is asked in a closed way –
such as ‘The following list shows things which people often like about their
holidays. Which are true about your last holiday?’ – we may be trying to achieve the
same objective but the responses will be quite dissimilar. The open question may
provide a wider range but will be more difficult to analyse, whereas the closed
question may provide a narrower range of responses (depending on how many items
are on the list) but will be easier to analyse. What could be lost in the closed question
are items that respondents would have stated were important but are not on the list.
Equally, with the open question, respondents may not remember things which were
important at the time (which a checklist might prompt) but are forgotten when
interviewed.
Unfortunately for the researcher, there is necessarily no absolute right or wrong
approach. The best solution, perhaps, is to reflect on the objectives of the survey and
include more than one questioning technique for each specific research objective.
This way the pros and cons of question types will be compensated for and a full
response will be provided overall.
