multiple moderation analysis
Hi,
I'm conducting moderation analysis with risk as the predictor, change as the moderator, and ethics as the outcome variable for four different scenarios (testing this moderation effect of change four times corresponding to four levels of risk and ethics).
I have two questions:
1- H1 model includes the predictor, moderator and interaction (predictor*moderator); to obtain R-squared change and report the interaction effect, the null model (H0) should include the predictor and the moderator or only the predictor?
2-how to address possible type I error resulting from conducting the moderation analysis four times? Each analysis tests the relationship between risk, change, and ethics within one scenario, with responses provided by the same participants across all four scenarios.
could you please suggest a video or learning material for moderation in JASP?
Thank you,
