Mean absolute deviation
Use consistent units. The result follows the assumptions you enter.

Formula
Use D = Σabs(xᵢ−μ)/n. xᵢ are observations, μ is their arithmetic mean, n is count, and abs means absolute value. D measures mean absolute distance from the mean.

Scope and limitations
Use consistent units. The result follows the assumptions you enter.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
