Arm Vs. Leg Length in relationship to Flexibility

Some classes ago, we worked on measurements regarding two body parts of children and how they could have an advantage based on the ratio of those body parts. My group worked with the ratio of arm length to leg length and how that could give them an advantage in flexibility. We measured the arm and leg length of 31 second graders. Here are the graphs for our group's research:

This graph shows the relationships of leg length and arm length in our sample.

This graph shows the arm vs. leg ratio in second graders in relationship to their skill.

This is a histogram concerning the frequency of each arm to leg ratio of second graders.
