The f ratio here is given by the ms for the group divided by the mss for the error.
00:10
And the ms for the group is defined by the ss for the group, which is 10 .258, divided by the degrees of freedom for the group, so which is three.
00:23
And then the ms for the error is 14198.
00:29
And this is 10.
00:31
So first you need to compute this ratio and this ratio, and then take the ratio of the ratios.
00:38
So if you compute this, you're going to find that the f here is 2 .483, which is 2 .41.
00:48
And the f critical here is given by, if you have like a f distribution here, we have alpha here.
00:57
So, half in our case, is 5%.
01:01
So we want to find this f here...
