A teacher wanted to see how listening to different types of music while studying could impact quiz scores. For each of her four classes, she had her students listen to a different genre of music while they studied (classical, country music, pop music, or classic rock). After studying with music for two days, she has her students take the quiz. She then averaged each class's quiz scores to graph and compare. What are the independent and dependent variables?
Independent - Genre of Music
Dependent - Average Quiz Score
