Quizplus · Accepted Answer

The group that listened to the calm music is the group that is being experimented on and is therefore the experimental group. The independent variable, in this case, is the calm music that they listened to, which is controlled by the researchers. The dependent variable, on the other hand, is the heart rate, which is being measured and is expected to change based on the experimental manipulation. The control group, in this case, would have sat quietly without any music but they are not the group being experimented on.
