Mean Absolute Deviation

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 data set.

Find the mean of the data.

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

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

Absolute deviation is calculated as |x - mean|, where x is the data point and mean is the average of the data set.

MAD helps to understand the variability in a data set and is useful for comparing the spread of different data sets.
