Now let's see what results we get for this data set right over here. And I'll do it, let me actually get some space over here. At any point, if you get inspired, I encourage you to calculate the mean absolute deviation on your own. 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.
