We figured out it and we totaled it all up. We got 6. So the sum of squares within was equal to 6. And in this case, it was 6 degrees of freedom. And we also had 6 degrees of freedom. Or if we wanted to write it generally, there were m times n minus 1 degrees of freedom. And actually, for the total, we figured out we had m times n minus 1 degrees of freedom.
