In a one-factor within-subjects ANOVA, the independent variable is held constant and all subjects are exposed to the same treatments. Therefore, the effect of the independent variable does not contribute to variation in scores since it is the same for all subjects. The individual differences among subjects (B) and the interaction of treatments and subjects (D) both contribute to variation in scores. However, the effect of the dependent variable (C) is not a relevant concept in the context of ANOVA, as it is the measure of interest being compared across treatments, not a source of variation.
