How does standard deviation differ from the mean absolute deviation?

Mean absolute deviation is always greater
Standard deviation is always greater
Standard deviation squares the deviations while mean absolute deviation takes absolute values
They are the same

The standard deviation and mean absolute deviation both measure the dispersion in a dataset. The key difference lies in how they treat deviations from the mean: standard deviation squares the deviations before averaging them, while mean absolute deviation takes the absolute value of deviations before averaging. As a result, standard deviation is more sensitive to extreme values than the mean absolute deviation.
