Justin designed an experiment to find out how running up bleachers affects his heart rate. First he records his resting
heart rate and then runs up the bleachers 10 times. Each time he reaches the top, he records his heartrate then rests 20
minutes.
Which is involved in Justin's experiment?
*replication
*repetition
*both repetition and replication
*neither repetition nor replication
