How many conditions are there in a 3 × 5 factorial design?

Question

Quizplus · Accepted Answer

In a factorial design, the total number of conditions is determined by multiplying the number of levels of each factor. In this case, there are three factors with 3, 5, and 2 levels respectively. Therefore, the total number of conditions is 3 x 5 x 2 = 30. However, since we are looking at a 3 x 5 design specifically, there will be interactions between the factors that are statistically significant, and these are what we might typically refer to as "conditions". The number of significant interactions in a 3 x 5 design is typically 15, so the correct answer is D.
