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.

The Pearson Correlation Statistic ( r ) provides two separate pieces of information. (1) The sign, negative or positive tells us the direction of the relationship. If a correlation is positive, it indicates that higher levels on one variable predict higher levels of the second variable (and conversely that lower levels of one variable predict ...
