Interactions describe how the effect of one factor depends on the level of another factor, and they can occur regardless of whether main effects are present. Main effects represent the individual effects of each factor on the outcome, while interactions show how these effects combine or change in the presence of each other, indicating that interactions and main effects are distinct concepts.
