The difference between causation and correlation, is that causation is when one event causes another one to happen. Correlation is not causation because two events can correlate, but that doesn’t mean that they caused each other. One example of causation could be because there was a large run of salmon, he got the most he has ever caught. One example of correlation is that there was a large run of salmon, and coincidently the new mayor is a great fisherman. There being a large run of salmon did not cause the new mayor, who is a good fisherman, to be elected. That’s a little confusing, you may have to read it more than once.
