The Mean Absolute Deviation (MAD)

EngageNY 45 min(s)

Students calculate the mean absolute deviation (MAD) for a given data set. Students interpret the MAD of a data set as the average distance of the data values from the mean. This lesson focuses on developing a more formal measure of variability in a data distribution called the mean absolute deviation, denoted by MAD. This lesson introduces the idea of a deviation as a distance and direction (to the right or to the left) from the mean and challenges students to think about why deviations provide information about variability in a data set.
