Quiz Score: 4/10

Comments: We noticed we were better at identifying problems of threats to internal validity, but had difficulty labeling the threats correctly. Our conclusion: we are looking forward to learning more about threats to validity by examining them through the lens of our own research. That said, let us know if you think we may have we mislabeled our threats to validity. :-)
