It is found that children’s shoe size is correlated with scores on an achievement test. Explain, in words, if this is evidence that correlation implies causation.

Explanation:

If you agree that increasing age (for elementary school children) causes increasing foot size, and therefore increasing shoe size, then you expect a correlation between age and shoe size. Correlation is symmetric, so shoe size and age are correlated.
