Scientific definition: a measure of how closely two factors vary together, or how well you can predict a change in one from observing a change in the other. Indicates a direct relationship, meaning that two things increase together or decrease together. Indicates an inverse relationship, meaning that as one increases the other decreases. Provides a statistical measure of how closely two things vary together and how well one predicts the other o. Refers to the perception of a relationship between two variables when only a minor or no relationship actually exist o. Refers to the tendency for extreme or unusual scores or events to fall back (regress) toward the average. No matter how strong the relationship, correlation does not prove causation.
