The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e., continuous variables measured on the interval or ratio scales).

The coefficient of determination can also be obtained by squaring the Pearson correlation coefficient. This method works only for the linear regression model = . The method does not work in general. The coefficient of determination, r2, represents the proportion of the total sample variation in y (measured by the sum of squares of deviations of ...

Pearson correlation coefficient - Wikipedia
1. The Pearson Correlation Coefficient. Correlation. In statistics, the word "correlation" has a very specific meaning. Statistical correlation means that, given two variables X and Y measured for each case in a sample, variation in X corresponds (or does not correspond) to variation in Y, and vice versa.

Pearson correlation r of log t90 and FITS1 = 0.975. P-Value = 0.000. If you look back to page 19, bottom, you will see that the correlation between log t90 and log t50 is also .975. That is, the correlation between the fitted (predicted) values and the observations y is the same as the correlation between the two variables x = log t50 and y ...
