Statistician William Hammack examined the relationship between the number of public schools in each county of Florida and the crime rate for the county. The data showed a very strong linear relationship, with r = 0.970. What can we conclude from this? There is probably a lurking variable at work. This relationship is totally meaningless. Public schools cause crime. We need more private schools.
