1-“Correlation is not causation” is a statistics mantra according to theguardian.com. “Correlation is not causation” means that just because two things correlate does not necessarily mean that one causes the other. Example provided by the article is as followed: just because people in the UK tend to spend more int eh shops when it is cold and less when it is hot, does not mean cold weather causes frenzied high-street spending; a more plausible explanation would be that cold weather tends to coincide with Christmas and the New Year sales.
