Research Methods in Psychology

How Do Psychologists Study the Mind?

Psychology is a science, which means researchers use systematic methods to collect and analyze data. There are a few major research methods:

  • Experiments: Researchers control variables to find cause-and-effect relationships.
  • Observations: Watching and recording behavior in natural or controlled settings.
  • Surveys and Interviews: Asking people about their thoughts or behaviors.
  • Case Studies: In-depth studies of a single person or group.

Why Are Methods Important?

Choosing the right method helps ensure results are accurate and reliable. Good research also means thinking about ethics—making sure participants are safe and treated fairly.

Key Concepts

  • Variables: Factors that can change or be changed.
  • Sample: A small group from a larger population that takes part in a study.

Learning how to design and critique studies is a core part of IB Psychology SL.
