Internal validity refers to the extent to which a study can establish a cause-and-effect relationship between the independent and dependent variables. It is important to check for internal validity to ensure that the results of the study are accurate and dependable. External validity refers to the extent to which the results of a study can be generalized to other populations or settings, while extraneous validity refers to controlling for other variables that may affect the results of the study but are not of interest to the researcher.
