PSYCH 530 Midterm: Midterm Review
Document Summary
The degree to which a measuring instrument produces the same results each time it is employed under a set of specified conditions. Same measure produces the same results the next time. Replication: depends how well the conditions of the prior research was spelled out, know exactly how it was used in prior research. The extent to which research finding are free from contamination by extraneous variables. Experiment measures what you intend to measure. The extent to which it is possible to generalize the results of one study to other populations, settings, or times. Have to take steps to increase validity: random sampling is better then volunteering and convenience sampling. In an experiment, the assignment of participants to experimental conditions on the basis of chance. The extent to which the experimental setting appears similar to natural, everyday situations. Low mundane realism does not imply low experimental realism.
