Which outcome is possible in a 2 × 2 factorial design?

C) No main effect for either factor and one interaction
D) A four-way interaction

A 2 × 2 factorial design can result in no main effects for either factor but still have one interaction effect. This design involves two factors, each with two levels, and allows for the examination of both the individual main effects of each factor and their interaction effect. However, it does not allow for two interactions or a four-way interaction, as those would require more factors or levels within the factors.
