- 43) Interactions between two continuous variablesNeed to standardise the scores (convert to Z-scores) Then multiply the 2 standardised predictors together.
Run MR with standardised P1 and P2 and interaction term (SP1*SP2) - 5Mediation?It's when the effect of one variable can have its effect on the criterion variable through another
- 6What's partial mediation?It's the effect of e.g. parties on exam performance is due partly to the fatigue cause by parties.
