Quizplus · Accepted Answer

For a between subjects factorial design, we need to have a separate group of participants for each combination of factors. In this case, there are four possible combinations (attractive/unattractive, female/male) so we would need 10 participants for each combination, resulting in a total sample size of 40 participants. Therefore, the best choice would be option D.
