About This Tool
The online Mean Absolute Deviation Calculator is used to calculate the mean absolute deviation of a set of given numbers.
Mean Absolute Deviation
In statistics, the mean absolute deviation is the mean of the absolute deviations of a set of data about the data's mean. The mean absolute deviation is also called the mean deviation.
Formula
For a sample size N and a data set {x1, x2, ..., xN}, the mean absolute deviation is calculated as following:
where
MD = mean absolute deviation
xi = the data element
x = the mean of the distribution
