Median Absolute Deviation

David C. Howell

Open publisher page 33 citations

Abstract

Abstract The median deviation is a measure of scale based on the median of the absolute deviations from the median of the distribution. For a normal distribution, the median deviation is somewhat less efficient than the standard deviation or the average deviation as a measure of scale, but this advantage quickly reverses for distributions with heavier tails.
