Answer to Question 1

The total sum of squares (SST) is equal to the within-group sum of squares (SSE) and the between-group sum of squares (SSB). In other words, SST equals the total sum of observed values' deviations from the overall or grand mean. It is computed by squaring the deviation of each score from the grand mean and summing these values (or squares). SSE, the variability that we observe within each group, or the error remaining after using the groups to predict observations, is calculated by squaring the deviation of each score from its group mean and summing these scores. SSB, the variability of the group means about a grand mean, is calculated by squaring the deviation of each group mean from the grand mean, multiplying by the number of items in the group, and summing these scores.
