Moderation analysis with a dichotomous moderator

I would like to run a moderation analysis with a continuous predictor variable, a continuous outcome variable, and a dichotomous moderator variable. Is it possible to do that in Jamovi? If so, which module is the best one to use?

yes, you can use GAMLj module (which provides also simple effects and simple slopes plots), but you can also use simply the "regression" command. In the latter case you need to center your variables before the analysis. In GAMLj they are centered by default
