A university researcher studies academic performance by comparing students who live on campus versus those who commute. She finds that on-campus students have higher GPAs and concludes that campus living improves academic performance. However, she later discovers that students with higher family incomes are more likely to live on campus, and family income correlates with academic resources and support. What would be the best way to strengthen causal conclusions about campus living?
