Document Summary
Theory: a formally stated and coherent set of propositions that explain and logically order a range of phenomena. Hypothesis: specific expectation or prediction about what should occur or be found if a theory is true or valid. Must be amendable to systematic testing that could show to be false. The focus of testing is on disproving rather than proving a theory. Case study collection of detailed biographical information. Can provide information about novel cases or procedures. Can disconfirm a relationship that was believed to be universal. Cannot provide casual evidence because alternative hypotheses cannot be eliminated. Correlation study of the relationship between tow or more variables, measured as they exist in nature. Widely used because we cannot manipulate many risk variables (such as personality, trauma, or genes) or diagnoses in psychopathology research with humans. Often used by epidemiologists to study the incidence, prevalence, and risk.
