Which relationship is likely ONLY a correlation and NOT one of causation?

gogolik [260]

"Correlation does not imply causation" is a phrase used in statistics to emphasize that a correlation between two variables does not imply that one causes the other. Correlation is the relationship between two sets of variables used to describe or predict information. Causation, also known as cause and effect, is when an observed event or action appears to have caused a second event or action.

Hope this helps. :)
