So let's calculate it. So the mean absolute deviation here, I'll write MAD, is going to be equal to, well let's figure out the absolute deviation of each of these points from the mean. So it's the absolute value of one minus three, that's this first one, plus the absolute deviation, so one minus three, that's the second one, and then plus the absolute value of six minus three, that's the sixth, and then we have the four, plus the absolute value of four minus three, and then we have four points. So one minus three is negative two, absolute value is two, and we see that here. This is two away from three. We just care about absolute deviation. We don't care if it's to the left or to the right.
