It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables. Pearson correlation coefficient ( r) Correlation type. Interpretation. Example. Between 0 and 1. Positive correlation. When one variable changes, the other variable changes in the same direction.STAT DIAGNOSTICS: OFF ON. OFF displays a statistical regression calculation without the correlation coefficient (r) or the coefficient of determination (r 2).. ON displays a statistical regression calculation with the correlation coefficient (r), and the coefficient of determination (r 2), as appropriate. displays a statistical regression calculationIt is possible to calculate the correlation coefficient from the means, variance and covariance, without actually having the original data points to begin with. The relationship is Correlation Coefficient = Covariance / ( (Std. Dev. (x) * (Std. Dev. (y)). The standard deviation is the square root of the variance.
