Finding Pearsons R Squared. Adjusted R2 1. So for example a Pearson correlation coefficient of 06 would result in a coefficient of determination of 036 ie r2 06 x 06 036.
For a pair of variables R-squared is simply the square of the Pearsons correlation coefficient. It helps in knowing how strong the relationship between the two variables is. The correlation coefficient r is directly related to the coefficient of determination r2 in the obvious way.
26 - Pearson Correlation Coefficient r.
Enter pairs of scores in SPSS using the data editor. This statistic represents the percentage of variation in one variable that other variables explain. Corresponds to the means of x and y respectively. Cor X Y Cor Ŷ Y Which is why in that special case.
