median absolute deviation  is a robust measure of the variability of a univariate sample of quantitative data. It can also refer to the population parameter that is estimated by the MAD calculated from a sample.

Some sites say it is the median diabsolute deviation and others say it is the mean absolute deviation.

I would have gone for the mean myself!

 

This video explains how to find it.
