Can you find any evidence for the reliability and validity of the quizzes on the websites?

You might frame your predictions in this form: "If this pop psychology scale were valid, it would be expected that it correlated with . . ." or "If this scale were reliable, it would be expected..."

Why or why not?

• Give examples of some questions you can ask to evaluate the external validity of a correlational study.
