This is going to be equal to, this right here is 2 minus 4 is negative 2 squared is 4. And then we have 3 4's over here. So it's 3 times 4 plus 3 times 0 plus, what is this? The difference between each of these, 6 minus 4 is 2, squared is 4. So we have 3 times 4 plus 3 times 4. And we get 3 times 4 is 12 plus 0 plus 12 is equal to 24. So the sum of squares, or we could say the variation due to what's the difference between the groups, between the means, is 24.
