I have a data that I'm calculating the average for a group of numbers using code below. Column P is the average of column N corresponding to the number in column C. See attached image. How do I calculate the standard deviation equivalent?
AVERAGEIFS(N:N,C:C,C2,N:N,"<>"&"")
AVERAGEIFS(N:N,C:C,C2,N:N,"<>"&"")
