Q
What is the difference between correlation and causation?
A
Correlation measures statistical relationship between variables (how they move together), while causation implies one variable directly influences another. Correlation doesn't imply causation due to confounding variables, reverse causation, or coincidence. Establish causation through controlled experiments, temporal precedence, and ruling out alternative explanations.
