### How is standard deviation different from mean absolute decation?

If I have understood the question correctly, despite your
challenging spelling, the standard deviation is the square root of
the average of the squared deviations while the mean absolute
deviation is the average of the deviation.
One consequence of this difference is that a large deviation
affects the standard deviation more than it affects the mean
absolute deviation.
