The questionnaire survey method is suitable for a single social group, such as closed stores, chain stores, restaurants, automobiles, real estate and other enterprises, to do some consumer satisfaction surveys, competitive product surveys, new product surveys and so on.

Questionnaire survey can ensure the objectivity of the survey results and avoid subjective deviation. Because the questionnaire survey is a structured survey, the form of expression, the order of asking questions, the ways and methods of answering questions are fixed, and it is also a way of writing communication. Therefore, it is impossible for any individual, whether a researcher or an investigator, to bring subjective prejudice into the investigation.

Because the questionnaire survey is a highly structured survey method, the survey results are convenient for statistical processing and analysis. As long as the language of the questionnaire is converted into a language (code) that can be recognized by the computer, the results of the questionnaire survey can be statistically analyzed by the computer.

Methods of questionnaire survey:

According to different methods, the questionnaire survey can be divided into four forms: mail questionnaire, newspaper questionnaire, send questionnaire and online questionnaire. In today's information network, online questionnaire survey is a common way, because it can break through the limitations of time and space, so the scope is wider. The network-based questionnaire survey method breaks the limitations of traditional passive survey methods in equipment, time and environment.

Respondents can use the mobile terminal equipment they carry with them to scan the code to participate in the survey anytime and anywhere, which greatly reduces the resistance and cost of respondents to participate in the survey; Through the breakpoint recovery function (you can continue to answer the next time you log in after answering part of the content), you can also effectively use the respondent's fragmentation time.
