Researchers are interested in investigating the link between music preference and grades in teenagers. They randomly sampled 200 Year 8 students, then randomly allocated one of four options to the students: listening to 30 minutes of classical music (and no other music) each day listening to 30 minutes of heavy metal music (and no other music) each day listening to 30 minutes of pop music (and no other music) each day listening to 30 minutes of country music (and no other music) each day At the end of two weeks, the researchers recorded each student's mark on a standardized maths test. Results showed that those students who listened to heavy metal music got higher marks, on average, than students who listened to other genres. Can you conclude that listening to heavy metal music causes higher grades? Researchers are interested in investigating the link between music preference and grades in teenagers.
