Research Question: Can the size of ones femur can be used to predict their height?

Variables: Femur size and height.

Both the femur and the height will be measured in inches.

I expect that there will be a positive association between the length of ones femur and their height because I think as the length of the femur increases, so will the height.

I'll probably use a measuring tape for measuring the femur and height and I will select people from Oxbow and probably my family members. Half will be boys and half will be girls.

Height = .293 (femur length) - 2.093

As I predicted, there was a strong, positive association between the length of one's femur and their height. As the length of the femur increased, so did the height. The correlation was 0.873 which is very strong. There were some things that could have affected the outcome such as not doing an even amount of boys and girls when measuring. Also, theres a possibility that the measuring could be off which would affect the correlation.
