What is Mean Absolute Deviation (MAD)?

Back

Mean Absolute Deviation (MAD) is a measure of the dispersion or spread of a set of data points. It is calculated by taking the average of the absolute differences between each data point and the mean of the data set.

In the context of MAD, what does 'absolute' mean?

Back

'Absolute' refers to the non-negative value of the differences, meaning we ignore whether the difference is positive or negative.
