Best Answer

The first step is to find out what the deviation is from: the mean, median, some other fixed value. Whatever it is, call it m.

For each observation x, calculate the absolute deviation, which is x - m or m - x, whichever is positive or zero. Finally, calculate the mean value (arithmetic average) of this set.
