Good video. Unfortunately, the 3rd and 4th moments are not quite correct. The formulas show mu to the 4th power. The exponents should be subscripts. That is, mu with a subscript of 4 is not the mean to the 4th power. Rather, it is the 4th central moment.

David, thanks. Untill now, I always judged visually whether a variable was normally distributed or not.
