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. Then we have another one minus three is negative two, but it's absolute value, so this is two, and that's this. This is two away from the mean. Then we have six minus three, absolute value of that's just going to be three, and that's this right over here.
