Stats 101 for journos or why CFCs aren't the culprit

A study into the impacts of CFCs on global warming has been covered in depth by sections of Australia's media. But there's one major problem with the research: correlation doesn't equate to causation.

I never really enjoyed statistics classes at university but it was a compulsory subject and so I had no other choice. While I’ve since found Microsoft Excel can do all the hard work I was forced to learn to do manually, there’s one thing it can’t cover off that I was taught about in Quantitative Methods 1 – correlation doesn’t necessarily equate to causation.
