In statistics, the median absolute deviation (MAD) is a robust measure of the variability of a univariate sample of quantitative data. It can also refer to the population parameter that is estimated by the MAD calculated from a sample. For a univariate data set X 1, X 2, ..., X n , the MAD is defined as the median of the absolute deviations from the data's median : Wikipedia
