Types of Questionnaires
Open format questions are those that ask for unprompted opinions. In other words, there is no predetermined set of responses, and the participant is free to answer however he chooses. Open format questions are good for soliciting subjective data or when the range of responses is not tightly defined. An obvious advantage is that the variety of responses should be wider and more truly reflect the opinions of the respondents. This increases the likelihood of receiving unexpected and insightful suggestions, for it is impossible to predict the full range of opinion. It is common for a questionnaire to end with and open format question asking the respondent for ideas for changes or improvements. This type of questionnaire provides qualitative data.

These type of questions provide quantitative data. There are two broad groups of closed questions they are dichotomous and multiple choice.
