QUESTIONNAIRESA、ADVANTAGES & DISADVANTAGES

Every coin has two sides and questionnaires are no different. With questionnaires, the advantages outweigh the disadvantages.

ADVANTAGES OF QUESTIONNAIRES

Compared to face-to-face interviews, questionnaires are cheaper for

collecting data from a large number of respondents. Also, questionnaires are easy to analyze, and computer software can easily complete data entry and make tables for nearly all surveys. Questionnaires are familiar to most people as nearly everyone has had some experience completing one. Questionnaires reduce bias when there are no clues to affect the respondents.

DISADVANTAGES OF QUESTIONNAIRES

One main disadvantage of questionnaires is the possibility of low response rates which reduces our confidence in the results. Another disadvantage is they provide little flexibility for the respondents. What’s more, many times the respondent is not the same person you sent the

questionnaire to. Finally, questionnaires are not suitable for some people. For example, a survey to a group of poorly educated people might not work because of reading problems.
