How to use the Mean Absolute Deviation Calculator
This tool uses deviations from the arithmetic mean. Absolute distances are averaged with denominator n, including for a sample.
The calculation
Mean absolute deviation = Σ|xi−mean(x)| / n
Worked example
For 1,2,3, the mean is 2 and the mean absolute deviation is 0.6667.
Assumptions and limits
This is not median absolute deviation and not standard deviation. It summarizes spread in the original measurement units without squaring distances.
