I'm not sure about the second formula (11 seconds into the video, written on someone's right forearm). Is that V or the Greek letter Nu? And what's df* mean? And is that eta or n on the bottom?
Very funny though.

I think it is Cramer's V.
I'm not familiar with the notation but I'm guessing the denominator is n(df*) and that df* is the smaller of the df for the two categorical varaibles - another way to represent this is n min(M-1,N-1) where M and N are the number of categories for the two variables you are calculating V for.
