Cause & Effect

October 30, 2010

“Cause and Effect”! You almost never hear these words in an introductory statistics course. The subject is commonly ignored. Even on this site, all it gets is this one web page. If cause and effect is addressed at all, it is usually by giving the (proper) warning “Association does not imply causation!” along with a few illustrations.

For example, in the early part of the twentieth century, it was noticed that, when viewed over time, the number of crimes increased with membership in the Church of England. This had nothing to do with criminals finding religion. Rather, both crimes and Church membership increased as the population increased.

There are more examples of this important principle at the address above.
