This project-based unit guides students in analyzing the cost of a college education through the use of algebraic and statistical skills. Students first research college investment options and make decisions based on longitudinal data and trends from a scatter plot. Then, students choose an appropriate regression model to analyze their data. The unit concludes as students analyze and share their findings and use these data to make practical financial preparations for college.
