Error sum of squares formula
WebThe sum of squares between had 2 degrees of freedom. The sum of squares within each of the groups had 6 degrees of freedom. 2 plus 6 is 8. That's the total degrees of freedom we had for all of the data combined. It even works if you look at the more general. So our sum of squares between had m minus 1 degrees of freedom.
