between-group variation

between-group variation

The variation due to interaction between the samples, which is the sum of squares between groups. If the sample means are close to each other, and therefore the grand mean, this will be small; there are k samples involved with one data value for each sample (the sample mean), so there are k-1 degrees of freedom.
