=== Median absolute deviation around the median ===
{{main|Median absolute deviation}}

The ''median absolute deviation'' (also MAD) is the ''[[median]]'' of the absolute deviation from the ''[[median]]''. It is a [[Robust measures of scale|robust estimator of dispersion]].  

For the example {2, 2, 3, 4, 14}: 3 is the median, so the absolute deviations from the median are {1, 1, 0, 1, 11} (reordered as {0, 1, 1, 1, 11}) with a median of 1, in this case unaffected by the value of the outlier 14, so the median absolute deviation is 1.

For a symmetric distribution, the median absolute deviation is equal to half the [[interquartile range]].
