To measure the interaction of independent variables,researchers would use a
A) pre-test-post-test control group design with the interaction observed before and after treatment
B) randomized block design with the interaction treated as the blocking factor
C) Latin square design with the interacting independent variables treated as levels of extraneous variables
D) factorial design

Only the factorial design allows breaking effects down to individual effects,main effects,and interaction effects of more than one independent variable.The RBD presumes that there is no interaction between the blocking factor and the independent variable,and the LS design assumes that there is no interaction between the two blocking factors.Only the factorial design allows measurement of the effect of interaction between independent variables.
