Within-groups sum of squares is also known as error sum of squares, denoted by SSW. It measures the variability within each group and represents the variation between individual observations and their respective group means. It is calculated by dividing SSW by (n - k). SSG, on the other hand, represents the variation between group means and is calculated by dividing SSG by (k - 1).
