Linear Regression: How does salinity of the ocean relate to depth?

Students in an introductory ecology and evolution lab collected water salinity measurements at various depths of the ocean at the Cal Poly Pier in Avila Beach, CA. Each student collected their own data and then worked through the attached activity to investigate correlation and simple linear regression. Use lab worksheet linked here. If your students are unable to collect data, you can use the data set collected at Cal Poly here.
