Mean Absolute Deviation

MAD is a measure of the dispersion of a set of data points. It is the average of the absolute differences between each data point and the mean of the data set.

True

To calculate the mean, add all the numbers in the data set and then divide by the total number of values.

Calculate the mean of the data set.

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

10

The absolute difference represents how far each data point is from the mean, regardless of direction.

0.66

6.48

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