N'ihe banyere calculator a

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. The MAD is expressed in the original units and is easy to explain to a non-technical audience. The MAD is 12 ÷ 5 = 2.4 — on average each value sits 2.4 units from the mean. The deviation table below lists every value’s distance so you can trace the result.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.Worked example: for 2, 4, 6, 8, 10 the MAD is 6. The absolute deviations are 4, 2, 0, 2, 4, 10.Worked example: for 2, 4, 6, 8, 10The MAD is 6, 2, 0, 2
