Write a short note on the ‘Advantage of Questionnaires’.
1. There is no doubt that questionnaries are very less expensive and for that reason quite attractive.
2. Questionnaire not merely save money but also it saves administrative time, talent and manpower e.g. by using the mail system instead of a costly adhoc staff of interviewers.
3. One special benefit lies in the simultaneity of access, if it is significant to reach all respondents at the same time, this is probably easier by means of questionnaries than interviews, unless the ratio of interviewers to interviewees is close.
