WHAT’S IN: A questionnaire is a research instrument consisting of a series of questions for the purpose of gathering information from respondents. Questionnaires can be thought of as a kind of written interview. They can be carried out face to face, by telephone, computer or post. Questionnaires provide a relatively cheap, quick and efficient way of obtaining large amounts of information from a large sample of people.

➢ Questionnaires

Closed form/ close-ended: Calls for short, checkmark responses. It is easy to fill out, takes little time, keeps the respondents on the subject, relatively objective, and is easy to tabulate and analyze.

• True or False test
• Yes or No test
• Multiple choice
• Statement with options (strongly agree, agree, not sure)

Open form/ open-ended: Calls for a free response in the respondent’s own words. No clues are given. The respondents reveal their frame of reference and possibly the reasons for their responses.

• Essay type questions
• Completion test (Science is _____)
• Definition of a term
• “Why did you choose to do your graduate work at this college?”

Guidelines in using Questionnaires

1. Clarity of Language – It should lead the respondents to give specific respondents and generate the desired information given.

2. Singleness of Purpose – It should elicit single piece of information or single response so that it will not confuse the respondent and make interpretation easy

3. Relevant to the Objective of the Study – Questions that do not serve the objective of the study should be eliminated.

4. Correct Grammar – To do this, the questionnaire must be edited or floated to

try-out respondents
