Why is Mean Absolute Deviation a better measure of volatility

WitrynaThe standard z score is calculated by dividing the difference from the mean by the standard deviation. The modified z score is calculated from the mean absolute deviation (MeanAD) or median absolute deviation (MAD). These values must be multiplied by a constant to approximate the standard deviation. WitrynaThen the median is subtracted from all samples in the input to find the deviation of each sample from the median. The median of all absolute deviations is then the MAD. The factor makes the MAD an unbiased estimator of the standard deviation for Gaussian data. The median absolute deviation has an asymptotic efficiency of 37%.

"WitrynaThe standard deviation is a measure of "spread", i.e. how far values vary from the mean. Adding the same fixed number to each output changes the "location" of each data point, but it doesn't change the spread. Multiplying each number by a constant doesn't change the location, but it changes the spread: multiplying by $2$ changes a gap of … " - Is standard deviation mad
