How to Calculate Absolute Deviation (and Average Absolute Deviation). In statistics the absolute deviation is a measure of how much a particular sample deviates from the average sample. ... Now we can calculate the absolute deviation. If we go to calculate the absolute deviation from the mean we take the mean average (6)

average absolute deviation - the average absolute deviation (AAD) is defined as ... In summary, the variance, standard deviation, average absolute deviation, and median absolute deviation measure both aspects of the variability; that is, the variability near the center and the variability in the tails.
