Mean Absolute Deviation Calculator
Calculate the mean and mean absolute deviation from a list of numbers.
Formula and assumptions
Calculates mean absolute deviation from the arithmetic mean, not median absolute deviation.
Results depend on the inputs and assumptions shown. Check units and independently verify important decisions.

Frequently asked questions
What is mean absolute deviation?
Mean absolute deviation is the average of the absolute distances between each data value and the mean of the data set.
How do you calculate mean absolute deviation?
Find the mean, calculate each value’s absolute distance from that mean, then average those distances.
Is mean absolute deviation the same as standard deviation?
No. Both describe spread, but standard deviation squares deviations before averaging and takes a square root, while mean absolute deviation averages absolute deviations.
