Moderation using SPSS

Does the effect of your independent variable change depending on a third variable? That's moderation — and in this video I show you how to run and interpret a moderation analysis in SPSS, step by step. Moderation answers one of the most important questions in research: not just "does X affect Y?", but "when, and for whom, does X affect Y?" Once you understand it, your analysis becomes far richer and more publishable. 📌 Best for: PhD students, dissertation work, and researchers testing conditional or interaction hypotheses in survey data. 🔔 Subscribe for a new research-methods video every Sunday. 💬 Working on a moderation hypothesis in your own study?
