Is finger length related to stature? It sounds to me like figuring out the answer to this question is the purpose of your school assignment. Because of that, I am going to be very sketchy with my response. About half of human stature is formed from long bones – the thigh bone (femur) and the leg bone (tibia). Although the fingers are relatively short compared to the lower limb, the finger bones (phalanges) are also considered to be long bones. Genetic features that influence long bone length in general will effect both the limbs (stature) and the fingers. So, you should expect to see relationship between the two values. In math this type of relationship is call a correlation. When you calculate it, correlation is a statement of the perceived relationship between two values. One does not necessarily cause the other – sometimes both are caused something else that has not been measured. So, when you ask if finger length effects stature – my answer is no. However, since both are effected by similar genes, you should find that the values are correlated.
