Document Summary
Multiple choice, definitions, one short answer. (5 pts each) Theories are concepts together by stating relationships between them. A theory consists of a set of propositions (for empirical generalizations) that are all logically related to one another. Inductive model of theory-building - theorize about it (info is in) Deductive model of theory building - come up with new tests to see if there is support for these new theories (need to find info) Deductive theory building process hypothesis empirical generalizations hypothesis. Generality - best theories are the ones who can be generalized to multiple contexts. Simplicity (or parsimony) - should be simple - there is not a whole lot of quantifications (no limitations) You can find a whole lot of things that are correlated, but they are not related. There can be a correlation, but not always a causation. Any property that varies (i. e. takes on different values) can potentially be a variable.
