What Psychological Research Methods Are For

This lesson explains what psychological research methods are for: not just collecting data, but turning everyday questions about thought, emotion, and behavior into answers that can be tested, checked, and improved.

Professor Daniel Martin introduces the core goals of research in psychology, including description, explanation, prediction, and control, and shows why good methods matter for separating evidence from intuition. The lesson also previews how research methods help psychologists build reliable knowledge while avoiding common mistakes such as bias, overgeneralization, and confusing correlation with causation.
