There are two types of questionnaires: open-ended and close-ended. Open-ended questionnaires do not provide answer options and require written responses, which respondents dislike and make analysis difficult. Close-ended questionnaires provide answer options for respondents to select from, such as a 5-point Likert scale, which is preferable and easier to statistically analyze. Well-designed questionnaires should have clear and specific questions that are free of assumptions and suggestions and are grammatically consistent.

1. Criteria for a good Questionnaire
1. The language must be clear.
2. The content of the question must be specific
3. The question should show singleness of purpose.
4. The question must be free from assumptions.
5. The question must be free from suggestions.
6. The question should have linguistic completeness and grammatical
consistency.
Two Kinds of Questionnaire:
1. Open-ended – options of the items are not given or not arranged. This
leaves the respondent to answer the question in his own way.
Example:
Directions: Please answer the following questions
1. Give your opinion on the issue of value- added tax
law_____________________________________________________
2. What is its advantage? __________________________________
3. What are its disadvantage? _______________________________
In general, respondents do not like to answer open-ended questionnaires. They feel
that they are taking the examination. Aside from this, an open-ended questionnaire
gives multiple responses, which makes statistical analysis difficult.
2. Close-ended Questionnaire – options or answers are given or enumerated
and the respondent simply checks or encircles his answer. It is better to
use a five- point likert scale.
Example 2
Directions: Encircle the number of the best answer. The options are the
following:
Stronger Agree - 5
