Marketing researchers have a choice of three main
research instruments in collating primary data; questionnaires, qualitative
measures and mechanical devices.
In this article let us discuss about the Questionnaire.
A questionnaire consists of a set of questions
presented to respondent. Because of its flexibility, the questionnaire is by
far the most common instrument used to collect primary data. Questionnaire needs
to be carefully developed, tested, and debugged before they are administered on
a large scale. In preparing a questionnaire, the researcher carefully chooses
the question and their form, wording and sequence. The form of the question can
influence the response. Marketing researchers distinguish between closed-end
and open-end questions. Closed-end question specify all the possible answers
and provide answers that are easier to interpret and tabulate. Open-end
question allow respondents to answer in their own words and often and reveal
more about the thoughts of the audience. They are especially useful in
exploratory research, where the researcher tries to get an insight into how
people are think rather than measuring how many people think in a certain
way.
Dos
And Donts of Questionnaire
- Ensure
that questions are not biased. Do not lead the
respondent into an answer. Let the respondent decide upon his own answer
without being prompted. - Make
the questionnaire as simple as possible. Do not make
the questions confusing by including multiple ideas or two questions in
one. - Make
the questions specific. It
is good to be specific with time periods while putting forth the questions
to the respondents - Avoid
jargons. Avoid trade jargons, acronyms and
initials which are not a part of daily language. - Steer
clear of sophisticated or uncommon words. Only
use words in common speech. The purpose of the questions is to know the
thoughts of the questions and not confusing them using uncommon words. - Avoid
ambiguous words. Words such as “usually” or “seldom”
etc have no specific meaning. They can be treated by individual
respondents in different way and thus can lead to wrong conclusions. As
stated earlier, questions should be specific. - Avoid
negative questions. It is better to ask “ Do you
ever…..” than “ Don’t you ever….”. - Avoid
hypothetical questions. It is difficult to
answer questions about imaginary situations. These answers cannot always
trusted. It is advisable never to ask questions related to products or
services of each the respondents have no clue. So, it is very necessary to
do a detailed study of the target audience before approaching the audience
with the questionnaire. - Avoid
using words that can be misheard or have multiple meanings. This
is specifically important for telephonic interview. - Desensitize
questions by using response bands. For questions that
ask people about their age or yearly turnover, it is best to offer a range
of response bands. - Ensure
that fix response do not overlap. Categories used in
fixed response questions should be sequential and not overlapping. - Allow
the option of
“other” in fixed response questions. Closed end questions should
always allow for response other than those listed.
