B)3
C)6
D)4

Question

Quizplus · Accepted Answer

There are four factors (independent variables) in a 2 x 3 x 6 x 8 factorial design. The first factor has 2 levels, the second has 3 levels, the third has 6 levels, and the fourth has 8 levels. To determine the number of factors, you simply count the number of variable conditions that are created by combining the levels of each of the factors. In this case, the total number of conditions is equal to 2 x 3 x 6 x 8 = 288, which indicates that there are four independent variables.
