Mean absolute deviation or MAD of a set of data is the average distance between a data point and the mean. To compute the MAD, students complete three steps. First, the average of the distances each data point is from mean is computed. Second, find the difference between each data value and the average. It is important to take the absolute value of that difference. Third, is to take the mean of each …

It is also termed as mean deviation or average absolute deviation. It can be calculated by finding the mean of the values first and then find the difference between each value and the mean. Take the absolute value of each difference and find the mean of the difference, which is termed as MAD. Find the MAD of a data set using this mean absolute ...
