independent variable
b. the main effects necessarily are artifactual
c. the simple effects of factor Aare equal to the main effect of factor B.

b. if Fobs for the interaction is nonsignificant
c. only if Fobs for the interaction and at least one main effect are statistically
significant

interaction is nonsignificant
