Questionnaire

A questionnaire is a set of questions that allows a researcher to ask different
people the same set of questions. This way we can find out a range of opinions
and response to a single product. This allows us to compare their answers on the
same basis. We can find out about the majority's consensus or extreme responses.

A questionnaire can include
closed questions and
• open-ended questions.

Closed questions provide a list of answers to choose from. The person answering
the question is limited to the given choices. Their answers may not be listed.
However, it is easy to organise data from closed questions.

Open-ended questions have no suggested answers. The person answering the
question can give a qualitative response. It can be difficult to organise data from
open-ended questions as you may get very diverse opinions.
