Brad Smith Challenge 2 Problem- The first day of lab, we were told that we needed to take measurements of our classmates sitting next to us. In centimeters, we measured standing height from the ground to the top of our heads. For sitting height, we were instructed to sit on a table and measure from the base of the spine to the top of the head. Leg length was measured from the ground to the top of the hip. Finally, arm span was taken, from both arms stretched out; we measured from the tip of one finger all the way across the body to the other side. After these measurements were taken, we were presented with the skeletal index. Hypothesis- If someone’s leg length is shorter, there will be a negative correlation to skeletal index. This statement means that if someone’s leg length is shorter; this will

Unformatted text preview: make their skeletal index larger. As skeletal length increases vertically, arm length expands horizontally at about the same rate. This means that as the vertical height increases, arm length should expand at an equal rate in comparison. Experiment- We only sampled the first 25 females on the first page and the first 25 females on the last page. After manipulating the data, we found the range for both graphs and the averages. They are as follows: Graph 1 Average leg height: 43.5 (range 36-51) Average skeletal index: 52.4 (range 48-56.8) Graph 2 Average leg height: 41 (range 36-46) Average skeletal index: 52.25 (range 49.7-54.8) Observations: After reviewing the data...
