There is a formula which gives the equation of the line of best fit. The equation of the line is . where and . Note: and . Note 2: and are the mean values of x and y respectively. This line is called the (least-squares) regression line of y on x (because the equation has been given with y the subject).

A transparent overlay for your scatter plot, including the line of best fit with two points on your line clearly labeled. Please indicate whether it is positive or negative correlation. You will then determine the equation of your line of best fit using the methods we used in class. All of the work should be shown on the poster.

Have them compare the linear-regression model to the equation of the line of best fit. Discuss what a correlation coefficient (R2) is and how its proximity to 1 indicates how the regression line fits the data. Give students the following data set and ask them to graph the points on a coordinate plane.
