ABSTRACT
A questionnaire may include a series of questions to be answered by an individual or group, with the aim of obtaining relevant data on the topic of research. Questionnaire is a data collection instrument. Some of the types of structured questions are Dichotomous questions, Level of measurement-based questions, and Filter or Contingency questions. Unstructured questions are used in interviews, where either the researcher does not prepare a list of questions and the series of questions might depend upon the response of the subjects or they ask questions in an informal atmosphere. The first step in questionnaire designing is arriving at preliminary decisions with regard to the issues of required information, the target respondents, and the interview techniques to be adopted. The next step is to determine the questionnaire content, so that it deals with identifying the need for data, the question’s ability to yield data, the participant’s ability to answer without generalizations, and the willingness to answer sensitive questions.
