Based on your review of the two studies, create a checklist to analyze the quality of research studies.

Your checklist should not have more than 20 items. Avoid repetition.
Explain how each item on the checklist helps evaluate a study.
The checklist should be clearly worded. A person using it should not have to ask for an explanation of any item.
