The following sets each have a mean of 50 and the standard deviations are given in variable form. Set I = {20, 20, 20, 80, 80, 80}, standard deviation = A Set II = {20, 30, 40, 60, 70, 80}, standard deviation = B Set III = {50, 50, 50, 50, 50, 50}, standard deviation = C Rank these three standard deviations from least to greatest.

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
