The SSA × S in a one-factor within-subjects analysis of variance represents.
A)variation due to the individual differences among subjects

Question

Quizplus · Accepted Answer

SSA (sum of squares for factor A) represents the variation due to the treatments (or independent variable).

S represents the total variation of the scores.

Therefore, SSA × S represents the interaction between the treatments and the subjects, also known as the treatments-by-subjects interaction.
