Quizplus · Accepted Answer

In a one-factor within-subjects ANOVA, SSA (Sum of Squares for the main effect) represents the variation due to the effect of the independent variable, as well as the interaction between treatments and subjects. SSS (Sum of Squares for the subjects) represents variation due to individual differences between subjects, SSA × S (interaction between the treatments and subjects) represents the interaction effect alone, and SSTotal represents the total variation in the data. Therefore, A is the best choice as it represents the variance due to both the main effect and the interaction effect.
