Generally speaking, you can double the sample size of the paper to check the copy or send it to an external audit to check it.

The most suitable sample size is about 300~500. If the graduation thesis involves questionnaires, there must be survey samples.

The sample size cannot be too small. The sample size is too small to explain the problem, so the basic sample size should be controlled at around 300~500. Only in this way can it be the support of the data in the paper and can it be passed in the evaluation process.
