The presence or absence of an interaction effect is crucial in interpreting the results of a complex design experiment involving two independent variables. An interaction effect suggests that the relationship between the two independent variables is not additive and may produce different outcomes depending on the level of the other variable. Without an interaction effect, the main effects of each independent variable can be examined separately. The total number of conditions and the number of statistically significant effects are relevant factors but do not determine the analysis plan or interpretation of the results.
