Thank you so much! I wish there were more videos like this. It was so clear and consice for those of use who are just trying to get a clear theoretical understanding of when and why to use certain tests.
Prof. Rio Grande: I understand for Point Biserial we need either Nominal vs Quantitative or Ordinal vs Nominal. Is that correct, or is it just with Dichotomous vs Quantitative?
Might as well have just given us slides, or made a podcast. The slides add nothing to what you are saying and vise versa. A visual representation would have been nice.

Is it possible to use three groups in the nominal variable?
you don't show how to do it. it would be nice if you sped it up a bit
excellent ...
It would be helpful if the video has graphical or visual presentation rather than just presenting texts
