What correlation is 'the taller the man, the larger the shoe size'?
Answers
This analysis shows that there is a linear correlation between foot size and height. We can expect people with large feet to be taller than people with small feet. However, there are a few sources of error in analysis which could be addressed in future studies. For one, shoe size is not a perfect measure of foot size. Some people may not be wearing shoes which fit them properly. It might be better to directly measure foot size. Also, men and women have different shoe size scales. A size 10 for women is smaller than a size 10 for men. If shoe size, rather than foot size, must be used, it might be helpful to break women and men apart in future studies. Nevertheless, since such a strong linear correlation was found in this study, I would expect to still find one in any future study.
