On the average, the heart rate does increase substantially when a person performs a physical activity between both men and women. For hypothesis (2), our results showed that men have a higher heart rate than women when the exercise heart rate was calculated, concluding that our hypothesis was incorrect. It is difficult to define how much effort the subjects put into the exercise. During the experiment, I scanned each individual to see what kind of exercise that they were doing. I noticed one individual doing jumping jacks, another talking while jogging in place and another jogging in place but at a faster pace. In all that was measured, the only thing that is controllable is the regular heart rate. There was not an independent variable because none of the values can be manipulated, everything was measured. In conclusion, all of these discrepancies can rationale an inaccurate measurement causing our hypothesis to be …show more content…
Larger hearts can pump more blood than smaller hearts in one beat. Another reason of low heart rate in men than women is capacity of lungs in men is 25-30% higher than women. Also, in clinical study the size of the heart is greater in men than in women. Men have more cardiac muscle than women do, therefore, men's hearts don't have to pump as much blood as often causing, lower heart rate.
In this experiment, there is not an independent variable because none of the values can be manipulated, everything was measured

What is the dependent independent variable in each of the experiments but the biggest flaw you can say about the experiment is that there really isn't a independent variable because none of the values can be manipulated everything was measured the only thing that is controllable is the regular heart rate
