Students will investigate cancer incidence rates in a number of states. Hypothesis testing is introduced and used along with a two-proportion z-test to compare cancer rates. This activity helps students to determine when a difference in data is actually statistically significant. This should encourage students to think carefully about claims made (for instance the presence of cancer clusters) and give them the tools to scrutinize these claims using statistical methods.
