4â¢ Describe outcome measure for study, how itâs calculated, and how itâs to be interpreted (you donât need to actually do calculations, but provide the equations and give an example of how theyâre interpreted): For example: RR=a/(a+b) interpreted as the risk of lung cancer in smokers is X times greater (or less) than it is in non-smokers

5â¢ Give justification for your study design (tell why you chose that particular study design, why it is appropriate, and what you hoped to learn from doing the study)
