Experimental Design: Music and Test Performance

A psychology researcher is interested in examining the effects of different types of music on students' test performance. They decide to conduct an experiment where one group of students listens to classical music while studying, another group listens to pop music, and a control group studies in silence. After studying, all students take the same math test, and their scores are compared.

In your response, describe the key components of this experimental design, including the independent variable, dependent variable, control group, and any potential confounding variables that could affect the results.
