You provided a very clear and well-organized explanation of when to use Pearson, Spearman’s rho, and the Chi-square test. I really liked how you emphasized the importance of choosing the right test based on the type of data and the distribution. That’s something students often overlook, but it makes a big difference in getting valid results. Your description of how Spearman’s rho works with monotonic relationships was especially helpful, it shows that not all correlations have to be linear to be meaningful.
