Internal validity refers to the degree to which we can confidently attribute changes in behavior to our independent variable rather than other extraneous variables. Therefore, if we are confident that our changes in behavior are actually caused by our independent variable, then our experiment has high internal validity. External validity refers to the degree to which our findings can be generalized to other populations and settings, which is not related to our ability to attribute changes to our independent variable. Replicability is important for establishing the reliability of our findings, but it is not directly related to our ability to attribute changes to our independent variable.
