A researcher measures a student's motivation to succeed as the amount of time spent studying. In a second study, the researcher conducts the same study but instead measures a student's motivation to succeed as the percentage of classes attended during a semester. Different results were observed in each study. What subcategory of external validity is low in this example? Explain.
What will be an ideal response?
Outcome validity is low because the outcomes in each study did not generalize across measures for the construct of student motivation to succeed.
