Average Deviation. In statistics, the absolute deviation of an element of a data set is the absolute difference between that element and a given point. The average deviation of a data set is the average of the absolute deviations. The average deviation is also called the average absolute deviation.
Statistics of the distribution of deviations are used as measures of statistical dispersion. 1  Standard deviation is the frequently used measure of dispersion: it uses squared deviations, and has desirable properties, but is not robust. 2  Average absolute deviation, is the sum of absolute values of the deviations divided by the number of observations. Median absolute deviation is a robust statistic which uses the median, not the mean, of absolute deviations.
