For example, questionnaire classification: the types of questionnaire design can be divided from different angles. If divided by investigation methods, it can be divided into interview questionnaire and self-filled questionnaire; According to the answer to the question, it can be divided into three types: structured, semi-structured and open;

First of all, according to the answer to the question.

Questionnaire can be divided into three basic types: structured, open and semi-structured.

1. structural formula.

That is, the so-called closed questionnaire or closed questionnaire. The answer of this questionnaire has been determined by the researcher on the questionnaire, and it is enough for the respondent to carefully choose an answer and circle or tick it.

2. open it.

Also known as unstructured or open. This kind of sentence paper has no fixed answer, so that returnees can play freely. Its characteristic is that there is no strict structural form in the setting and arrangement of questions, and subjects can answer freely according to their own wishes. Unstructured questionnaire is rarely used as a separate questionnaire. When some questions need further investigation, it is often used in combination with structured questionnaire.

3. Semi-structural structure.

This kind of questionnaire is between structured and open. The answers to the questions are both fixed and standard, and some of them are freely played by the respondents, drawing on the advantages of both. This kind of questionnaire is widely used in actual investigation.

Second, according to the survey method.

According to the survey methods, questionnaires can be divided into: self-filled questionnaires and interview questionnaires.

Self-administered questionnaire is a questionnaire filled and answered by the respondents themselves. Self-filled questionnaires are divided into two categories: sent questionnaires and mailed questionnaires due to different sending methods. Sending a questionnaire is a survey form in which the investigator directly sends the questionnaire to the interviewed voice and the investigator directly recovers it. Mailing questionnaire is a form of investigation that is directly mailed by the investigation unit to the respondents, who fill in the answers themselves and then mail them back to the investigation unit.

The interview questionnaire is a questionnaire filled out by the interviewer through the interview voice. The interview questionnaire has the highest recovery rate and the most reliable results, but it costs a lot and takes a long time. Generally, the recovery rate of this kind of indirect paper is required to be above 90%. The process of questionnaire survey is uncontrollable, and its credibility and effectiveness are low. Moreover, due to the low recovery rate, the sample will be biased, which will affect the report of the sample to the whole.
