Students deepen their understanding of this content by investigating questions such as: How have incomes for higher- and lower-income individuals in the U.S. changed over time? How much income inequality exists between males and females in the U.S.? Does education explain the wage gap between males and females?

This module was developed for 12th grade non-AP mathematics and statistics courses and contains seven lessons and one final team data investigation. The module is designed for two to three weeks of instruction.
