According to this site, which is a top google search site, "The higher the coefficient, the higher percentage of points the line passes through when the data points and line are plotted. If the coefficient is 0.80, then 80% of the points should fall within the regression line. " Is this true? Does $100r$ value give us the percentage of points that lie on a linear regression curve.
On another site I see the image I posted below, and it shows very few points that lie on the line of best fit , but the $r$ value which is about 0.95 is relatively high.
