Distinction Between Correlation and Causation
A statistical correlation simply indicates that two variables have moved together, without explaining the underlying reason. In contrast, a causal relationship, or causation, is a more restrictive concept implying that a change in one variable directly produces a change in the other. Establishing causation requires identifying a specific mechanism that accounts for the observed association, going beyond the mere assessment of a shared trend.

The Hypothesis of Government's Role in Post-War Economic Stabilization
An examination of long-term US economic data shows that the period of greater economic stability (fewer and smaller recessions and booms) that began after World War II coincided with a substantial increase in total government tax revenue as a percentage of the nation's total economic output. What is the most accurate conclusion that can be drawn solely from this observed relationship?
The observed increase in the size of the U.S. government after World War II, measured by tax revenue as a share of GDP, is the proven cause of the reduced economic volatility seen in the same period.
