So in general, let's figure out the degrees of freedom here. You have, for each group, when you did this, you had n minus 1 degrees of freedom. Remember, n is the number of data points you had in each group. So you have n minus 1 degrees of freedom for each of these groups, so it's n minus 1, n minus 1, n minus 1. Or you have, let me put it this way, you have n minus 1 for each of these groups. And there are m groups. So there's m times n minus 1 degrees of freedom.
