Formula and methodology
Formula: Mean absolute deviation=Σ|xᵢ−x̄|/n.
This spread measure stays in the original units and uses absolute distances rather than squared deviations.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Data values — Comma-separated finite numbers.
Worked example
| Input | Value |
|---|---|
| Data values | 1, 2, 4, 7, 9 |
Mean =4.6; mean absolute deviation =2.72.
Assumptions and limits
- Values are numeric observations measured on a comparable scale.
- The arithmetic mean is the center for the deviations.
- Sampling uncertainty and a robust median-centered alternative are not modeled.
