What is the Mean Absolute Deviation (MAD)?

Back

MAD is a measure of the dispersion of a set of data points around their mean, calculated as the average of the absolute differences between each data point and the mean.

Back

Mean.

Front

What is the formula for calculating the Mean Absolute Deviation?

Back

MAD = (Σ|x - mean|) / n, where x is each data point, mean is the average of the data, and n is the number of data points.
