How well a regression fits the points

Explanation:

With a $R^{2}$ $R^2$ value close to 1, we the regression would fit the points perfectly:

Since the $R^{2}$ $R^2$ isn't 1 the points won't fit the line perfectly even though the $R^{2}$ $R^2$ value is so high.
Since the $R^{2}$ $R^2$ is so high the graph would be accepted. Typically the lower limit is approximately $R^{2} = 95$ $R^2 = 95$ for a good graph.
