Enter the correlation coefficient displayed in the applet. correlation coefficient: Now add another data point, in the upper-left corner of the scatterplot. This causes the correlation coefficient Then click and drag this to point down to the lower-left corner of the scatterplot. Take note of this new correlation coefficient and how it changed when you dragged the point down.
