T   F  1. All of the core premises of the philosophy of science have been empirically tested and confirmed.

   T   F  2. Epistemology is a theory of the nature and grounds of knowledge.

   T   F  3. When science cannot explain something, it engages in what is known as mystification of residuals.

   T   F  4. A good conceptual definition is inclusive and stated negatively.

   T   F  5. Active variables cannot be manipulated by the researcher.

   T   F  6. Operational definitions link concepts in the realm of abstractions with empirical observation.

   T   F  7. A relationship is said to exist when particular values of one  variable tend
                 to co-occur with particular values of another variable.

   T   F  8. Concepts are tentative answers to research questions and are expressed
                 in the form of  relationships between independent variable and dependent variable.

    T   F  9. A good research design should control the variance of the extraneous
                  variables and minimize error variance.

   T   F  10. Extrinsic threats to internal validity involve changes in the subjects, the
                  measuring instrument, or reaction to being measured.

   T   F  11. In some ex post facto designs temporal order of the variables can  be safely assumed to exist.

   T   F  12. Since all forms of control, other than randomization, require planning
                  which extraneous variables are to be controlled, you must review the literature
                  to identify the extraneous variables that represent the greatest threat to the
                  hypothesis being tested
