In a two-way factorial design without interaction, the total sum of squares (SS_total) is partitioned into the sum of squares due to factor A (SS_A), factor B (SS_B), and the within-group sum of squares (SS_wg). Therefore, the correct formula reflects this partitioning: SS_total = SS_A + SS_B + SS_wg.
