Document Summary
Internal validity technical quality of study, how well the study has been done and whether it avoids confounded variables. The less chance for confounding variable, the higher the internal validity. Use double blind procedure: hawthorne effect people acting a different way because they know they are in a study and are being watched, over-generalizing generalizing experimental findings beyond the conditions of the original experiment. If the same score is btained when a measurement is repeated, the measurement is said to posses high reliability. Interclass reliability based on the correlation between trials. Intraclass reliability based on variation across trials: test-retest method doing the tests again to see if you get consistent results, split-halves method test split into two parts. Independent groups design experimental design in which each treatment condition is administered to a separate group of subjects: simple random assignment most common method of assigning subjects to independent groups.
