Investigation 2-2
Compared To What?

 Students examine the need for a control group and have more experience in using a 2x2 table.  First, students learn how risks are calculated from the 2x2 table.  Students then compare the risks of disease among the exposed and unexposed groups of people.  This calculation is called a relative risk.  From the relative risk, students learn to make inferences based on the similarities or differences between two risks. Students realize that a hypothesis can only be tested when risks of getting a disease are compared among exposed and unexposed groups.  They also learn the importance of calculating a relative risk by realizing that the same risk of getting a disease in the exposed group (for example 10%) may lead to different inferences depending on the rate of disease in the unexposed group (10%, 1%, or 40%).
