Experiment by moving the data points around and seeing how the correlation coefficient r changes.
Next, arrange the ten data points to make the correlation as close as possible to a target value. If you are working in a classroom, compare your results with other students.
Suggested targets: r = 0.6, r = -0.6; r = 0.99, r = -0.99; r = 0.3; r = -0.3; r = 0.
Notice that moving points that are close to the center of the data distribution has a different impact than moving points that are further out.
