The tutor said that she should change the data analysis in her thesis, and don't question the authority of the tutor. If you want to revise it, it should be that your paper has obvious argumentation errors. You must carefully check and revise it, and communicate with your tutor more to get high marks.

Under normal circumstances, the teacher will not let you demonstrate the process of data analysis when defending, but will generally ask you the theoretical basis of the paper, how the data was collected (that is, through what channels), your questionnaire design, data analysis results, conclusions and so on.

In other words, people who are not academic or experienced for a long time can generally clearly see the clues in the sorted data results. It is recommended not to cheat, which is the most despised and unacceptable in academic circles. This is a more serious mistake than the wrong frame of your paper.
