Fractile v. Equal Lesson for Grades 7-10

Students work with data that represent the ages of 24 people to learn the difference between categorizing data in fractile intervals and equal intervals. Students discuss dividing bonus points among class members to understand what per capita means. Then students look at per capita personal income by state using the GeoFRED mapping tool. They compare per capita personal income displayed with data in equal intervals and with data in fractile intervals.
