According to the questionnaire survey of college students, how to distribute the questionnaire is more reasonable? There are about 20 thousand people in the school and 200 questionnaires.

One of the methods of questionnaire sampling selection: reverse deduction from results to survey topics. The general survey method is to approach the survey results from the respondents, but this method may not be useful to us. If we deduce from the survey results to the survey topic, we can roughly know how many samples are needed, how much the survey process is, and so on. Perhaps through this method, we can get the best investigation benefit and reduce the investigation to the lowest cost.

The second method of questionnaire sampling selection: sampling survey. Sampling survey can be divided into typical sampling or key sampling survey. Typical investigation is to select cases with typical characteristics from model essays for investigation; Focus investigation refers to the most reasonable and effective data investigation to effectively improve its best investigation effect. The two methods use different methods, and the final result may be the same, but the specificity of the result may also be different. So for us, when choosing a sample survey, we also need to consider it from all angles, so as to get the best survey results.
