Correlation does not imply causation[edit]

Hi, in the article Correlation does not imply causation, on 15 October 2015, you added a section, "The relationship between A and B is coincidental". This contains the statement "5% of things will correlate by chance at a 95% confidence level". Whilst I'd agree that random correlations are real, do you have a citation for the stated amount? A quick Google search failed to to find a match. I've added a [citation needed] tag, but if you could remember, and add, where the quote came from, it would be useful.

The 95% confidence level means that 5% of the time, you'd expect the result to happen by chance; that's what 95% confidence *means*. 95% is a common confidence level used in a lot of scientific papers. It's the old jelly beans thing. I'll see if I can find a formal cite from a book in my closet. See confidence interval for a discussion of it. Titanium Dragon (talk) 22:50, 28 March 2016 (UTC)
