nollyMy stats and related classes were too long ago.
Given a set of numbers -- integers,in this case, but I don't think it matters -- I want to detect whether they're all clustered (180, 180, 183, 179, 181), clustered with a small number of outliers (180, 179, 360, 182, 184), or spread (180, 300, 200, 250. 275). Number of input points could be anywhere from 2 to 50, maybe more. Do I want to use population standard deviation, sample standard deviation, population variance, sample variance, or something else?
