Quizplus · Accepted Answer

To calculate the total number of participants needed in a factorial design, we multiply the number of levels for each IV and then multiply that by the number of participants in each cell. In this case, the first IV has 3 levels, the second IV has 2 levels, and there are 10 participants in each cell, so the total number of participants needed is 3 × 2 × 10 = 60. Therefore, the best choice is B.
