Choose two variables that appear to have a relationship that is worth investigating. One variable should have at least two categories of individuals—for example, two or more age categories, racial categories, or geographical locations. The other variable should have at least two categories for some social, economic, or health factor— for example, two or more income categories, drinking categories, or educational attainment categories. Find the frequency data needed to fill in a two-way table for the two variables. Carry out a hypothesis test to determine whether there is a relationship between the variables. A good data source is a website for the Statistical Abstract of the United States produced by the U.S. Census Bureau.
