Suppose a friend of yours is telling you about a study reported in a popular magazine. The friend said that the study reported a correlation of zero between the amount of coffee a person drank as a child and his or her height as an adult. Your friend interprets this correlation to mean that the more coffee a child drinks, the shorter that person will be as an adult. In other words, drinking coffee stunts one’s growth. Explain what is wrong with your friend’s interpretation and explain what this type of correlation means.
