If a two-factor analysis of variance produces a statistically significant interaction, then what can you conclude about the interaction? either the main effect for factor A or the main effect for factor B is also significant both the main effect for factor A and the main effect for factor B are significant neither the main effect for factor A nor the main effect for factor B is significant the significance of the main effects is not related to the significance of the interaction
