Document Summary
Dependent variable: in an experimental study, the phenomenon that is measured and expected to be influenced (compare with independent variable) External validity: extent to which research findings generalize, or apply, to people and settings not involved in the study. Hypothesis: educated guess or statement to be tested by research. Independent variable: phenomenon manipulated by the experimenter in a study and expected to influence the dependent variable. Internal validity: extent to which the results of a study can be attributed to the independent variable after confounding alternative explanations have been ruled out. Research design: plan of experimentation used to test a hypothesis. Testability: ability of a hypothesis, for example, to be subjected to scientific scrutiny and to be accepted or rejected, a necessary condition for the hypothesis to be useful. Analogue model: approach to research that employs subjects who are similar to clinical clients, allowing replication of a clinical problem under controlled conditions.
