PSYC 217 Lecture Notes - Lecture 14: Dependent And Independent Variables
Document Summary
Learning objectives: explain an interaction effect using simple main effects. Interpret interaction effects from different types of factorial designs. If not, there is an interaction effect meaning that the effect of one variable depends on the level of the other variable. Remember: main effect: effect of one of your independent variables on the dependent variable, ignoring the effects of all other independent variables. Changing the order of the effects changes the story and main effects are qualified by an interaction between the two independent variable. Simple main effects refer to the effect of one iv on the dv within a single level of the second iv. More dogs will sit when you tell them to sit rather than not telling them to sit if you hold food in your hand. If (cid:455)ou do(cid:374)"t have food i(cid:374) (cid:455)our ha(cid:374)d, telli(cid:374)g the dogs to sit does (cid:374)ot affect the proportio(cid:374) of dogs that sit.
