B) $X - \bar { X } _ { A B }$
C) $X - \bar { X } _ { G }$
D) $X + \bar { X } _ { A B }$

Quizplus · Accepted Answer

B) $X - \bar { X } _ { A B }$ represents the deviation of an individual score from the mean of the cell (combination of levels of factors A and B) it belongs to, which is a measure of within-cells or within-groups variation, not accounted for by the effects of the factors being studied.
