A questionnaire is a form prepared and distributed to secure responses to certain questions. It is a device for securing answers to questions by using a form which the respondent fills by himself. It is a systematic compilation of questions that are submitted to a sampling of population from which information is desired.
Questionnaire rely on written information supplied directly by
people in response to questions. The information from questionnaires tends to fall into two broad categories – ‘facts’ and ‘opinions’. It is worth stressing that, in practice, questionnaires are very likely to include questions about both facts and opinions.
Types or Forms of Questionnaire:
1. Structured Vs. Non-structured Questionnaire: A structured questionnaire contains definite, concrete and directed questions, whereas non-structured one may consist of partially completed questions or statements. A
non-structured questionnaire is often used as the interview guide, which is non-directive.
2. Closed form Vs. Open form
The questions that call for short check responses are known as restricted or closed form type. They provide for marking a ‘ yes or no’ short response. It restricts the choice of response for the respondent.
The open form including open end or unrestricted type of questions calls for a free b response in the respondent’s own words. No clues are provided. It probably provides
for greater depth of response.
