Webf Standard deviation vs. mean absolute deviation : STANDARD DEVIATION : *SD squares distances, penalizing longer distances. * std : sqrt (variance) more than shorter ones. *MAD penalizes each distance equally. np.std (msleep ['sleep_total'] , ddof=1) *One isn't better than the other, but SD is more. common than MAD.
