Project 4. Association is not causation. Write a snappy, attention-getting article on the theme that “association is not causation.’’ Use pointed but not-too-serious examples like those in Example 6 (page 348) and Exercise 15.30 (page 364) of Chapter 15, or this one: there is an association between long hair and height (because women tend to have longer hair than men but also tend to be shorter), but cutting a person’s hair will not make him or her taller. Be clear, but don’t be technical. Imagine that you are writing for high school students.
