In this topic you have discovered the very important correlation coefficient as a measure of the linear relationship between two variables. You have derived some of the properties of this measure, such as the values it can assume, how its sign and value relate to the direction and strength of the association, and its lack of resistance to outliers.

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.

On tests, you won't have to compute the correlation coefficient. For these data, we have r = 0.927. Is this consistent with your guess? 5. On your scatterplot, guess where you would draw a line that comes close to describing the data. Do a very light sketch of it. You will compare your guessed line with the one you actually compute below. 6.
