The advantages and disadvantages of the questionnaire survey method are:

First, the advantages of the questionnaire survey.

1. Unity: The questionnaire survey uses the same questionnaire to ask questions for all the respondents, which is beneficial to the comparative analysis of the respondents in the same situation, and can also investigate the respondents with different consciousness from the society and analyze the individual situation.

2. Extensive: the questionnaire survey is not limited by the number and scope, and the range of possible answers given in the design is generally selected by the respondents, which is also convenient for the respondents to understand the survey content. Because the questionnaire survey is mostly conducted in a closed way, because in the process of data collation, the answers can be coded and data input for quantitative processing and analysis.

second, the shortcomings of the questionnaire method. Design-oriented questionnaire survey is difficult, the questionnaire design is difficult, and the survey results are wide but not deep. The questionnaire survey is often completed by users themselves, so the quality of the survey results is often not guaranteed, and the recovery rate of the questionnaire survey is difficult to guarantee.
