  • Now that you know a bit about correlation, it’s important to understand that correlation does not imply causation. In other words, just because two variables are related does not mean that one of the variables caused the other. This is a common logical fallacy that leads to invalid conclusions. Check out this Los Angeles Times article that makes the point that correlation does not imply causation. Then to drive the point home, visit the site that inspired the article, Spurious Correlations, to view a variety of amusing graphs showing two completely unrelated variables that just happen to be closely correlated.
