Answer

To draft a questionnaire or schedule is an art. The success of statistical investigation depends on proper drafting of the questionnaire. It is a highly specialized job and following points should be borne in mind:
  1. Brief and Limited Questions: The number of questions in a schedule should be brief and limited as far as possible. Only relevant questions to the problem under investigation should be added. Ideally it should be between 20-30.
  2. Simple and Clear: The questions should be simple, clear and precise. Its language should be very simple so that informants may easily understand.
  3. Unambiguous Questions: All unambiguous questions should be avoided at all, complicated and long-worded questions irritate the respondents which results in careless; replies.
  4. No Personal Questions: No personal question should be asked from, e respondents. Such questions should be avoided. For example,
  • Do you take alcohol?
  • Do you tell a lie?
  • Does your boss scold you?
  1. Use of Proper Words: Questions should be framed with right words. This ensures the validity. Starting a question with negative is undesirable. For example, Don't you think India is a corrupt country?
  2. Avoidance of Calculations: Questions should not be based on calculations. Only those questions should be asked which the respondents may reply immediately. Moreover, questions should avoid memories.
  3. Preference to Objective Questions: The objective type questions should be given preference. Either MCQ or yes no options should be given but in case of need and requirement of investigation, open ended questions can also be used.
  4. Logical Sequence of the Questions: The arrangement of the questions should be such that it involves a logical flow of questions. For example it is not sensible to ask a person:
  • What is your income?
  • Are you employed?
OR
  • How many kids do you have?
  • Are you married?
  1. Pre-testing: Before sending the questionnaire to the respondents, it must be properly tested. It will let investigator know the loopholes of questionnaire which he can rectify.
  2. Instructions: Precise and simple instructions of filling the questionnaire should be added in the foot note.
  3. Cross Examination: The questionnaire should be set in such a way that there may be cross examination of the information supplied by the informants. In fact, it is a check on false or inaccurate answers. For example, asking age as well date of birth is cross checking of right information
  4. Secret Outlay: Every respondent should be ensured that information given by them shall be kept secret.
  5. Attractive Questionnaire: Proper care should be taken to make the questionnaire attractive. A well set questionnaire will certainly impress the recipient.
