Earth Science Fall Benchmark Revieww

A student wanted to test to see if students who study with music earn higher test grades than students who study without music. He got a group of 30 8th graders together and had them listen to music in a room temperature room while they took a test. He got another group of 30 students together and had them listen to no music while they took their test. Each student took a 40 question multiple choice test. The student concluded that listening to music negatively affects test scores.
