Median of Absolute Deviations
Estimate spread round sample median with method wey resist extreme values.
Your numbers
Median of absolute deviation values
Use consistent units. Result follow the assumptions wey you enter.

You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
Use D = median(abs(xᵢ−median(x))) and scaled value 1.482602218505602D. xᵢ na observations, median dey pick di middle of sorted values, and abs mean absolute value. Di scaling dey give normal-consistent spread estimate.
Estimate spread round sample median with method wey resist extreme values.
Example wey show the calculation
- Values wey you observe
- 1, 1, 2, 2, 4, 6, 9
- Median of absolute deviation values
- 1
- MAD wey scale to match normal-distribution spread
- 1.48260221851
- Median
- 2
Where e fit work and limits
Use consistent units. Result follow the assumptions wey you enter.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
