What is Mean Absolute Deviation (MAD)?

Back

Mean Absolute Deviation (MAD) is a measure of the dispersion of a set of data points. It represents the average distance between each data point and the mean of the dataset.

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 of each result. 3. Find the average of these absolute values.

Front

What does it mean if the MAD is low?

Back

A low MAD indicates that the data points are close to the mean, suggesting less variability in the dataset.

Front

What does it mean if the MAD is high?

Back

A high MAD indicates that the data points are spread out over a wider range of values, suggesting more variability in the dataset.
