Carrie conducted an experiment to see if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. She had 10 volunteers. Each of the first 5 volunteers listened to seven different music selections for 30 seconds each. The person’s pulse was taken before the music and after each 30-second interval of music was completed. The other 5 volunteers did not listen to music and had their pulse taken every 30 seconds for 5 minutes. Based on her experiment, Carrie concluded that a person’s pulse rate did change when the person listened to different types of music. Identify the control group, the experimental group, the independent variable, and the dependent variable.
