Questionnaires are documents which consist of multiple questions which are all directly or indirectly linked to a particular topic. Such questionnaires are different from one another and can be categorised into many different blocks or categories. These categories are based upon the nature or use or aim of the questions in the questionnaire. There can be many different classifications of questionnaires but we shall discuss a straight forward and easy to understand categorisation.

  • The first major category of a questionnaire is a structured and non disguised questionnaire. This category is one which has questions in a well structured or ordered manner. In this category questions are set in a pre arranged manner and respondents are told about the very purpose of the questionnaire. This type is quite clear to understand and follows a strict format.
  • The next category of questionnaires is a structured and disguised questionnaire. This category too is an ordered one but what makes this one different from the first category is the fact that respondents are not told about the purpose or use of the questionnaire. One can say that this category doesnt have a strictly followed pattern because users are not made clear of the type of questions.
  • The next category is the non structured and non disguised one. In this category, the questions may not necessarily be arranged in a well set manner but the respondents are informed about the use or purpose of the questions. The researcher who has framed this questionnaire may not follow any specific sequence while framing such type of questionnaires.
  • The next and the last category is the non structured disguised category of questionnaires. This category, as the name suggests is one which has no order of questions and plus the users are not informed about the purpose of the questions posed in front of them.
