The main reason to use a 2 x 2 factorial design instead of two separate experiments (with one IV per experiment)is to
A) find the main effects of each independent variable.
B) find an interaction between the independent variables.
C) save time.
D) There is no good reason to use a 2 x 2 design if you can conduct separate experiments instead.

Question

The main advantage of using a 2 x 2 factorial design is to investigate the interaction between the two independent variables. This allows for a more nuanced understanding of the relationship between the variables than can be gained from conducting two separate experiments. While there may also be some time-saving benefits to using a factorial design, the primary goal is to better understand the interaction between the variables. Additionally, the factorial design allows for the examination of main effects as well as the interaction effect, which can add further insight into the nature of the relationship between the variables.
