What is Mean Absolute Deviation (MAD)?

Back

The average distance between the data values and the mean.

Front

How do you calculate the Mean Absolute Deviation?

Back

1. Find the mean of the data set. 2. Subtract the mean from each data point and take the absolute value. 3. Find the average of those absolute values.
