'To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean' https://www.geogebra.org/m/UaMEvgyH#:~:text=To%20find%20the%20mean%20absolute,%7Cdata%20value%20%E2%80%93%20mean%7C.
