$$\frac {\sum_{i=1}^N (x_i-u)/N}{p^4}$$
Is it only top part of the fraction including the N or just whatever is in the parenthesis. I'm making a code that includes this equation and I need to put it in a loop so that is why I am asking. Also pretend the p and u are numbers they already declares I just did not know how to put it on here so they are placeholders.
