The independent variable in Dr. Chen’s study is:
**a. Whether students listened to upbeat music before the test**
This is because the independent variable is the factor that is manipulated or changed in an experiment to observe its effects on the dependent variable, which in this case relates to the music listened to (upbeat music versus no music) before the math test.
