Type Of Variables

If a question is asked at the midterm or final term about finding the variables from the text. Should we only focus about the independent variables and dependent variables? Or should we have to include confounding, mediating and moderating variables too?

Nonparametric tests

A couple of months ago, I have shared my research proposal with you. It was about detecting the software supply chain attack vulnerabilities from the online package repositories like (npm, maven central, pypi).

There was a part where I had to find out the correlation of the factors which are associated and how much associated for a codebase / package being malicious.

Since the dataset wasn't following a normal distribution, I had used Shapiro-Wilk test for that.

During the non-parametric lecture of chapter 3, you have shown us a reference from wiki where it was said that: the non-parametric test is used to identify whether the samples originate from the same distribution.

Does this mean that my approach is wrong for finding out the correlation between the factors and the dataset by following the above method?

During my statistical analysis class under Professor Iskandar, I have known that random sampling from the dataset makes it look like a normal distribution.

May I know your opinion on this?
