Carmen conducted an experiment to determine 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. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music. What is the independent variable in Carmen's experiment?

a)

The pulse rate of each person

b)

The type of music played

c)

The time spent listening to each type of music

d)

The room each person was in when listening to the music
