Mean Absolute Deviation Calculator

Calculate the arithmetic mean and the average absolute distance of the data values from that mean.

Enter values and select Calculate.

Formula and methodology

Mean absolute deviation = Σ|xᵢ − x̄| / n. This calculator uses deviation from the arithmetic mean, not median absolute deviation.

Worked example

For 2, 4, 6, 8, the mean is 5; deviations are 3, 1, 1, 3; and mean absolute deviation is 2.

Assumptions and interpretation
