A process or relationship in which one factor produces a change in another.
A relationship in which one factor causes a change in another.
A positive correlation supports a possible relationship, but does not prove causation on its own. Link it to the mechanism of fossil-fuel combustion and greenhouse warming.
Keep conclusions within the conditions and range of the data. A correlation alone does not prove causation.
When evaluating causation, explain how a proposed mechanism connects the factor to the outcome, and consider other factors that could explain the correlation.
