Researchers have found that statistically, there is a direct positive relationship between students' shoe sizes and their results on spelling tests and spelling bees. (That is, students with larger shoe sizes tend to do better.)

Can you explain this correlation?

those with a larger shoe size tend to be older thus possessing a greater deal of "spelling" knowledge than those with smaller shoes or smaller ages.
