EXAMPLE 2 Racial differences in six-year graduation rates

Because there are only two categories of graduation status, we can see the relationship between race and graduation status by comparing the percentages of those who completed a bachelor’s degree within six years for each race:

More than 60% of the White students and almost 70% of the Asian students completed a bachelor’s degree within six years, but only about 40% of Black students and 50% of Hispanic students completed a bachelor’s degree within six years.
