Causation and lurking variables
Over a period of years, the population of a certain town increased. It was observed that during this period the correlation between x, the number of people attending church, and y, the number of people in the city jail, was r= 0.90. Does going to church cause people to go to jail? Is there a lurking variable that might cause both variables x and y to increase?
