A researcher wants to know whether listening to different types of music when studying helps students get higher scores on their math tests. Students listen to classical, country, hip hop, or pop music while studying for a math test. In the control group, students do not listen to any music at all while they study. At the end of the experiment, students take their math test and the results show that students who listened to classical music got the highest scores on the math test out of all the groups. |
