Quizplus · Accepted Answer

In an independent-measures, two-factor study, each participant is assigned to only one cell in the design, resulting in four groups for each combination of the two factors. Therefore, the total number of separate groups of participants needed in this study would be the product of the number of levels of factor A (3) and the number of levels of factor B (4), which is 12.
