## About This Tool

The online Median Absolute Deviation Calculator is used to calculate the median absolute deviation of a set of given numbers.

## Median Absolute Deviation

In statistics, the median absolute deviation (MAD) is a measure of statistical dispersion and it is a robust measure of the variability of a univariate sample of quantitative data.

## Formula

The median absolute deviation (MAD) is calculated as the median of the absolute value of each value, x_{i}, minus the median:

MAD = median(|x_{i} - median(x_{i})|)
