^I don’t really know myself. I think the point of StDev is to “punish” those that are further away from the mean. That is, a deviation of 20 should be “punished” more than 10 deviations of 2.
And facts being what they are–other than one part of one paragraph in Level 1, you’ll probably NEVER see MAD again in the CFA curriculum. |
