mean absolute deviation (MAD) is the average distance between each value and the mean, using absolute values so distances never cancel out. It measures spread like the standard deviation but is simpler and less sensitive to outliers, because it does not square the deviations. This calculator reports the MAD together with the mean, range and the sum of absolute deviations it was measured from. This calculator reports the MAD together with the mean, range and the sum of absolute deviations it was measured from. This calculator is easy to explain to a non-technical audience and it is easy to trace every value’s distance so that you can get the result.The method is direct: find the mean, take the absolute value of each value’s distance from it, add those distances up and divide by the number of values. The MAD is 12 ÷ 5 = 2.4 — on average each value sits 2.4 units from the mean.Worked example: for 2, 4, 6, 8, 10 the mean is 6. The absolute deviations are 4, 2, 0, 2, 4, which sum to 12, so the MAD is 12 ÷ 5 = 2.4Worked example: for 2, 4, 6, 8, 10 the mean is 6. The absolute deviations are 4, 2, 0, 2, 4, which sum to 12, so the MAD is 12 ÷ 5 = 2.4Worked example: for 2, 4, 6, 8, 10The MAD is the average distance between each value and the mean, using absolute values so distances never cancel out.Worked example: for 2, 4, 6, 8, 10The MAD is the average distance between each value and the mean, using absolute values so distances never cancel out.Worked example: for 2, 4, 6, 8, 10The MAD is the average distance between each value and the mean, using absolute values so distances never cancel out.Worked example: for 2, 4, 6, 8, 10The MAD is the average distance between
