3. A research study with a factorial design is set up where
there are two independent variables (gender of
participant and age of participant) and the dependent

remembered more than males. We can say that there is
a(n) _______________ of gender of participant.
a) main effect
b) interaction effect
c) simple effect
d) null effect
