To test hypothesis that a causes b, experiment seek to isolate, control, and manipulate a determine its effect on b. *theory: a general proposition of how people behave/think, or when they might behave/think in a certain way. *hypothesis: specific prediction of behavior/thought given a specific situation. *variable: any factor within a piece of research that can take on a different value (i. e. it varies) that can be measured. **independent variable: theoretical construct that we predict has impact on the thoughts/behaviors of people. Usually presence/absence of quality expected to lead to change (e. g. new batteries vs. old batteries) **dependent variable: the phenomenon that we attempt to influence with our experiments. : uncontrolled in the strict sense, free to vary. Dv - the dv depends on the iv. 1. great for precision and control 2. make more confident causal statements. Replication with other studies, other methods, other operational definitions of same construct cf) problems with vague definitions:
