Correlation vs. Causation Explained

Paul Henne, a philosophy graduate student, explains the difference between correlation and causation using examples like Andy's math test performance and weather conditions. He highlights common fallacies where people mistake correlation for causation, emphasizing the need for evidence to establish causal relationships.
