Olivia is studying for a test, and she wonders if her friend, Laney, is also studying for the test. She calls Laney and asks her how long she has been studying. Laney has been studying for her test all week, approximately 8 hours total. Olivia has only been studying for her test for a couple of hours. The next week, Olivia and Laney get their test scores back. Laney got an A on her test, and Olivia got a C. Olivia wonders if there is a correlation between the number of hours spent studying and the grade a student earns. Take a look at the data Olivia collected from her classmates, and see if you can find a correlation.
