Common questions
Is this the same as median absolute deviation?
No. This tool averages distances from the arithmetic mean. Median absolute deviation takes the median of distances from the median.
How does Mean absolute deviation about the mean work?
Find the arithmetic mean, then average the absolute distances of observations from that mean.
What should I check before using Mean absolute deviation about the mean?
Uses the units and scope stated in the input labels. Results are rounded for display; verify the model is appropriate for your situation.
