Correlation vs. Causation: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on November 28, 2023
Correlation indicates a relationship between two variables without implying one causes the other. Causation means one variable directly impacts or causes changes in another.

Key Differences

Correlation refers to a mutual relationship or connection between two or more things. Causation, on the other hand, implies that a change in one variable is responsible for a change in another.

Correlation can be positive, negative, or zero, suggesting different types of relationships. Causation, however, asserts a direct cause-and-effect relationship where one event is the consequence of another.

Observing a correlation between two variables doesn’t automatically mean there's a causal relationship. Without further investigation, assuming causation can lead to false conclusions.

It's possible for two variables to have a strong correlation because they're both influenced by a third variable, not because one causes the other. Causation requires more stringent evidence, typically through controlled experiments.

Simply put, while correlation can hint at a relationship between two variables, causation explicitly states that one variable is the reason for the change in another.

Understanding the difference helps avoid drawing incorrect conclusions and making uninformed decisions.
