Identify the experimental units or subjects, the explanatory variables (factors), the treatments, and the response variables.A student project measured the increase in the heart rates of fellow students when they stepped up and down for three minutes to the beat of a metronome. The step was either 5.75 or 11.5 inches high and the metronome beat was 14, 21, or 28 steps per minute. Five students stepped at each combination of height and speed.
