In a factorial experiment, the number of simple effects analyses that can be conducted depends on the number of levels of the independent variables. Because a separate analysis of each independent variable is conducted at every level of the other independent variable, the total number of simple effects equals the sum of the levels of all interacting independent variables. For example, a $$2 	imes 2$$ design yields $$4$$ simple effects, a $$2 	imes 3$$ design yields $$5$$ simple effects, and a $$3 	imes 3$$ design yields $$6$$ simple effects.
