Calculate the mean absolute deviation — the average distance of each value from the mean.

How It Works

How Mean Absolute Deviation Calculator Works

Every value's distance from the mean is measured (ignoring whether it's above or below, hence "absolute"), and those distances are averaged — a simpler, more intuitive spread measure than standard deviation, though standard deviation remains more common in formal statistics.

FAQ

Frequently Asked Questions

How is this different from standard deviation?
Standard deviation squares each deviation before averaging (which penalizes large deviations more heavily) and then takes a square root to return to the original units — MAD skips that squaring step entirely, making it simpler to compute and interpret, but less commonly used in inferential statistics.
