Since Pearson's correlation coefficient is a more appropriate measure than Spearman’s rank order correlation when summing random variables in risk modeling (see Reference 3), we will concentrate on this correlation measure. By definition, Pearson's correlation coefficient (Pearson’s r) calculated between two sets of numbers {xi} and {yi} is ...

Find the Pearson correlation coefficient for the relationship between the gender and GPA, and then prepare a scatter plot, with linear fit line, for predicting GPA (the vertical, Y axis) from gender (the horizontal, X axis). You will find that this line runs from the one group mean to the other group mean.

How to Calculate Pearson Correlation Coefficient: 9 Steps
A Pearson correlation coefficient (r) describes the strength and direction between 2 interval and/or ratio variables (x and y). Because there are 2 variables, this relationship is assumed to be linear. A correlation coefficient ranges from –1 to 1. The number indicates the strength of the relationship and the sign (+ or …
