*** Notice that the standard deviation uses the difference between each entry x and the mean x bar. The quantity (x – x bar) will be negative if the mean is greater than the entry. If you take the sum Σ (x – x bar) then the negative values will cancel the positive values, leaving you with a variation measure of 0 even if some entries vary ...
