its a physiology of exercise lab based on the measurement of aerobic oxygen consumption. Its a paper lab where you’re supposed to calculate only either subject 1 or subject 2 and graphing both subjects data. I would prefer for the calculations to be based on subject 2. And for the graphs it is a scatter graph and a linear graph for both subject 1 and subject 2 done on excel, please include the “r value” on all graphs.
