Front

What does it mean if the Mean Absolute Deviation is low?

Back

A low Mean Absolute Deviation indicates that the data points are close to the mean, showing less variability.

Front

What does it mean if the Mean Absolute Deviation is high?

Back

A high Mean Absolute Deviation indicates that the data points are spread out over a wider range of values, showing more variability.
