Correlation Coefficient: Simple Definition, Formula, Easy Calculatio…
Understanding the Pearson Correlation Coefficient (r) 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).

Comment on the significant correlations. Be sure to indicate the direction of the correlation (i.e., the higher variable A score the lower variable B). Also calculate and report the Coefficient of Determination for each significant correlation. State what this coefficient tells us. Next for all pairs of continuous variables, produce a scatterplot.

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.
