A questionnaire is a form containing a set of questions, especially one that addresses the statistically significant number of subjects as a way of gathering information for research or survey. In other words, a questionnaire is a research instrument consisting of a series of questions for the purpose of gathering information from respondents.
The following are disadvantages of the questionnaire as a data collection tool in research:
- Pre coded questions may bias the findings towards the researcher.
- A questionnaire sent through post-offer little opportunities to check the truthfulness of the answer.
- Since respondents are required to read and respond to questions asked, the questionnaire can not be used for illiterate and children.
- Since the auditor will be required to send questionnaires to respondents and wait for them to reply by filling them, this makes the questionnaire slow as compared to another method of collecting data such as interviews.
- There is a high chance that respondents will not answer and return the questionnaire sent to them.
