The Mean Absolute Deviation (MAD) of a set of data is the average distance between each data value and the mean.

The steps to find the MAD include:
1. find the mean (average) of all values
2. find the difference between each data value and the mean
3. take the absolute value of each difference
4. find the mean (average) of these differences
