In statistics, a measure of the strength of the relationship between two variables. It is used to predict the value of one variable given the value of the other. For example, a correlation might relate distance from urban location to gasoline consumption. Expressed on a scale from -1.0 to +1.0, the strongest correlations are at both extremes and provide the best predictions. See regression analysis.
