The sum of squares for error is used to measure the amount of total variation that is unexplained, as it represents the variation within each treatment group that cannot be accounted for by the treatment itself. The sum of squares for treatments measures the variation between the treatment groups, and the total sum of squares is the sum of both the sum of squares for treatments and the sum of squares for error. The degrees of freedom are used to calculate the sum of squares for each component.
