What is the difference between cause and correlation?
Correlation means two variables change together (an association), while causation means one variable directly causes the other to change; the key difference is that correlation doesn't prove cause-and-effect, often due to lurking (confounding) variables or coincidence, requiring controlled experiments (like A/B tests) to establish true causality. Think of ice cream sales and shark attacks: both rise in summer (correlated), but hot weather (a third variable) causes more swimming, increasing both, not the ice cream itself
