Correlation A correlation exists when two different measures of the same people, events, or things vary together—that is, when scores on one variable covary with scores on another variable. A positive correlation indicates that, as the values for one measure increase, the values for the other measure also increase In a negative correlation, as the value of one measure increases, the value of the other measure decreases “correlation does not imply causation.” Knowing that two variables are correlated does not allow us to infer that one causes the other (even if one precedes the other in time).

Correlation and Research Correlational research provides a basis for making predictions. Relationships among naturally occurring variables are assessed with the goal of identifying predictive relationships. Correlational evidence, in combination with a multimethod approach, can help researchers identify potential causes of behavior. Correlational evidence can contribute, however, to identifying causal relationships when used in combination with sophisticated statistical techniques (such as analyses of mediators and moderators in path analysis) and the multimethod approach.
