Generally speaking, the questionnaire data in graduation thesis will not be checked. If there are many questionnaires in the paper, there will be the results of the questionnaire survey. As long as it conforms to the routine, in most cases, the school will not check the students' original questionnaires. However, if there is a serious phenomenon that the survey results are inconsistent with the facts, students are likely to be required to provide the original questionnaire.
