Here is a scatter plot of the weights and corresponding heights of the individuals in the study. This also includes a line of best fit. Discussion 1. 2. Based on the data that I have collected the results are very comparable to the data supplied by the anthropometric reference data. The average (height) that I got for males was around 176.78 cm and they recorded 176.3 cm. These are very close numbers. The average weight in the class for males was 76kg (165lbs) for males and 69kg (152lbs) for females. However, these averages do not correspond to the numbers recorded in the supplied data sheet. Their average weight was around 194lbs. I think this deviation can be because they used a much larger group (4500 people) to conduct their study, in my study there were only 10 participants. This could be a plausible explanation for the vast different in average weights between what I got and what the supplied data sheet has. Conclusion Upon completion of this section in the lab I feel the most significant finding I noticed was that some individuals are taller than others because they have longer legs because when you compare their sitting heights they are really close for some people. For example one participant was at least 4 inches taller than another individual but their sitting height was only about a 2 inch difference. This can be attributed to one person having longer legs and another having a longer torso. Also, my results showed that my subjects mean values for height were comparable to the heights measured in the supplied data sheet. However, the mean values for weights were different. The mean values for weight in the supplied data sheet were about 20 lbs heavier than my subjects. Part 2: Measuring Heart Rate and Blood Pressure Purpose The purpose of this component was to become familiar with using the various tools used to obtain blood pressure and to see how your heart rate and blood pressure responds to different body positions and low intensity exercise.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
