What is the Mean Absolute Deviation (MAD)?

Back

The Mean Absolute Deviation (MAD) is a measure of the dispersion 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.

How do you calculate the mean of a data set?

Back

Add all the numbers in the data set and divide by the total number of values.

What does absolute value represent?

Back

The absolute value of a number represents its distance from zero on the number line, regardless of direction.

What is the formula for calculating Mean Absolute Deviation?

Back

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