Regression and Correlation
1. Drag the points around the graph and watch how the value of, r, the PMCC (Correlation Coefficient) changes. 2. Can you arrange the points so that r=1 or as close to 1 as you can get. 3. Now arrange the points to make r as close to -1 as you can get. 4. Clik the check box to show the equation of the line of best fit. 5. Move the points so that they have integer coordinates and then clacvulate the line of regression of y on x using your techniques from S1.
