Correlation & Causation

Some people use loosely the terms "correlation" and "direct correlation" to imply "causation" between two variables. It is a known fact in statistics, however, that correlation does not imply causation. To avoid such "logical fallacies", one may want to review a basic statistics textbook and / or the work of Browne & Keeley in their excellent book entitled: "Asking the Right Questions: A Guide to Critical Thinking".
