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. Which component is missing from Carmen’s experiment?
a)
A control group
b)
a hypothesis
c)
a description of the experiment
d)
the conclusion
31.
Why is a control group necessary when making an experiment?
a)
a control group has nothing done to it, compared to the group we are experimenting on. Thus, we can see if our experiment produces a change.
b)
We need something to change, and that is what the control group is
c)
We need to state what procedure we are going through in our experiment.
d)
We need to have an idea of what we're changing.
