How Correlation Between Two Variables Doesn’t Necessarily Prove That One Causes the Other

Mitchell Moffit and Gregory Brown of AsapSCIENCE explain the concepts of logical fallacy, lurking variables, confounding variables and show how correlation doesn't necessarily prove causation.

Unfortunately this does not always equal that even though it may look like it.
