The coefficient of determination is a number between 0 and 1, inclusive. That is, If r2 = 0, the least squares regression line has no explanatory value. If r2 = 1, the least-squares regression line explains 100% of the variation in the response variable.

( Coefficient of Correlation (or simply, correlation) COEFFICIENT OF DETERMINATION (R2) Defn: Coefficient of Determination, R2, = = proportion of the total variability in Y explained by a linear relationship to X. NOTES AND COMMENTS. 1. R2 is always between 0 and 1. 2. R2 = 1 is a “perfect” fit, all the points fall perfectly on a line. 3.

If there is no correlation, r2 is equal to zero. Correlation coefficient, r, the square root of r2--positive or negative, depending on. the type of correlation--range -1 to +1. Note: ρ (rho) and ρ2 are the population parameters corresponding to r and r2. Correlation and causation. The presence of correlation does not, in itself, prove that x ...

The square of the correlation (r2) gives the proportion of criterion variance that is accounted for by its linear relationship with the predictor. In other words, the square of the correlation coefficient equals the proportion of the total variance in Y that can be associated with the variance in X.

r2: The coefficient of determination: A measure of strength of relationship. Compare r = .50 with r2 = .25. r is an ordinal measure of strength of relationship. r is not particularly useful for getting a “feeling” for how strong a relationship is. r2 is viewed by many as giving a better picture of strength of relationship.

The percentage of shared variance is represented by the square of the correlation coefficient, r2. Another way to visualize this is with a Venn diagram that represents the amount of shared variance, or overlap of variation, of two variables. Because r-square is interpreted as the percentage of shared variance, it is best to compare two r2s ...
