How does causation differ from correlation?

• A. Correlation is a numerical relationship only
• B. A relationship of association that does not imply one event caused the other
• C. Causation explains why events happen and leads to outcomes
• D. A random coincidence with no underlying explanation

Answer: (C)

The main idea is that causation means one event brings about another, explaining why something happens and what results follow. It requires a believable mechanism and a clear sequence in time, showing how changing one factor directly affects another. Correlation, by contrast, is simply that two things tend to occur together; they move in tandem, but that togetherness doesn’t prove that one causes the other. In history, you might notice a correlation between factors like rising literacy and greater political participation, but you haven’t proven causation until you show how increased literacy led to that participation and rule out other explanations. So the statement that causation explains why events happen and leads to outcomes captures the essence of the difference. A description that correlation is merely a numerical relationship is too narrow, and saying it’s just a random coincidence ignores real cases where a causal link or a shared cause exists.
