In this episode of The Psychology Undergrad, we dig into what makes research credible, valid, and replicable. Learn how psychologists define variables, design experiments, and balance control vs. realism in their studies. We unpack key terms like independent/dependent variables, validity, reliability, and confounding variables, with clear examples—from sleep and stress studies to moral decision-making. Plus, we explore how truth-seeking in science mirrors faith’s call to integrity and discernment. Perfect for anyone studying research methods, preparing for exams, or trying to understand how psychologists separate real effects from noise.
