I have ten sets of data, each having ten data points within. I want to compare the standard deviation among all ten sets to see which has the widest distribution and which the narrowest.
My simple question is, should I use STDEV.S or STDEV.P for to calculate the standard deviation of each data set? I assume I should use P, since the entire population of each data set consists of the ten data points within it. But I wanted to check that off with the group here.
Please advise? Thanks.
