*Review the McHugh & Welk readings and the Determining Risk Calculations handout in this week's lesson introduction and the Determining Risk PowerPoint presentation in the Instructional Materials section.
Then, answer the following questions:
Calculate the incidence rate (IR) for dropping out of high school. How do you interpret this result (in your own words)?
What is the attributable risk (AR) of dropping out of high school for adolescent females who become pregnant? How do you interpret this result (in your own words)?
Calculate the relative risk (RR) of dropping out of high school for adolescent females who become pregnant. Assuming your RR is significant, how do you interpret this result (in your own words)?
