PSYB01H3 Study Guide - External Validity, Factorial Experiment, Internal Validity
Document Summary
Chapter 14: generalizing results: internal validity refers to the ability to infer that there is a causal relationship, external validity is the extent to which the findings may be generalized. Generalizing to other populations of research aprticipants: rarely are participants randomly selected from the general population. Important to realize that males and females may respond differently to questions or o manipulations of the variable. Locale: participants in one locale may differ from ones in another locale, results obtained with a set of participants in one locale may not generalize to other locations. Including variables such as gender, age or ethnic group in the design of the study o the results may be analyzed whether there are interaction effects. Are post test scores based on dependent variable different because of a pretest. Generalizing from laboratory settings: does the artificiality of the laboratory setting limit the ability to generalize what is observed in the lab to real-life.
