Four minus three is one, absolute value is one, and we see that. It is one to the right of three, and so what do we have? We have two plus two is four, plus three is seven, plus one is eight over four, which is equal to two. So the mean absolute deviation, let me write it down, it fell off over here. Here for this data set, the mean absolute deviation is equal to two, while for this data set, the mean absolute deviation is equal to one. That makes sense. They have the exact same means.
