Correlation and Causation Discussion

I’m working on a mathematics question and need an explanation and answer to help me learn.

1. The world is awash with people confusing correlation with causation – and the implications of this mistake are often enormous. Sometimes correlation exists because of an underlying causation, but sometimes (even when it seems like there should be – or you just REALLY want there to be causation) the correlation isn’t driven by any correlation. Please come up with your own (don’t just google) significant real-world example where correlation exists, but it may likely not be causal. Explain how regression analysis could point this out.
