PS295 Lecture Notes - Lecture 8: Grou, Pygmalion Effect, Internal Validity
Document Summary
Internal validity: the degree to which a researcher draws accurate conclusions about the effects of the independent variable. Degree to which a study allows accurate conclusions about the effects of an iv on. Degree to which we can condifidently conclude that differences observed on the the dv. External validity: refers to the degree to which the results obtained in one study can be replicated/ generalized to other samples, research settings and procedures. The generalizability of the research results to other settings. There may sometimes be trade- offs between internal and external validity: features that produce high internal validity may produce lower external validity. Experimenters dilemma: the more tightly the experiment controls the experimental setting, the more internally valid the results but the lower the external validity. Mundane realism: features of a study that are similar to what you would encounter in everyday life.
