O one main effect is significant and one main effect is not significant. O the effects of one IV depend on the particular level of another IV. O the independent variables operate independently from each other. Question 10 1 pts Suppose you design an experiment that had one IV with two levels, one IV with three levels, and another IV with four levels. What is the shorthand notation for this design? O 1 x9 O 1 x 24 O 2 x3 x4 O 1 x 2 x3
