Median Absolute Deviation Calculator

The median absolute deviation, often abbreviated MAD, measures the spread of observations in a dataset. It is calculated as:

MAD = median(|xi – xm|)

where:

  • xi: The ith value in the dataset
  • xm: The median value in the dataset

This calculator finds the median absolute deviation for a given dataset.
