explain the difference between causation and correlation based on " the fishing at rock point was terrific this year thanks to the largest run of salmon in 20 years. I caught a half dozen king salmon , the most i'ver ever caught! plus, we started fishing on the day the salmon run was at its highest , and there were no other fishermen there. we had the entire river and all the fish to ourselves. my uncle was listening to the radio while we fished, and he heard that Rockport had elected a mayor on the same day. he says the mayor is a great fisherman and will do a good job"
