Questionnaire Method


A Questionnaire consists of a number of questions printed or typed in a definite order on a form or set of forms. This method is quite popular, particularly in case of big enquiries. It is being adopted by research workers, private an public organisations and even by governments. The questionnaire is mailed to respondents who are expected to read and understand the questions, reply to the questions and send it back. The respondents have to answer the questions on their own.
