A very wide range of research methods are used in psychology.
Some of the approaches include:
- Correlational research
- Observational study , in which researchers study a population while attempting to change as little as possible.
- Experimental study , in which researchers change a variable in the group being studied.
- Prospective study , in which a study samples subjects as the experiment progresses. Cf. Retrospective study.
- Retrospective study , in which data is collected on subjects' histories at one time. Cf. Prospective study.
Longitudinal study, in which subjects are studied over a course of time. Cf. Cross-sectional study.
Cross-sectional study, in which a snapshot of the population is assumed to represent individuals as they progress through life. See also Longitudinal study.
