When a scatter plot shows a linear association, you can use a line to model the relationship between the variables. A trend line is a straight line that comes closest to the points on a scatter plot. Joyce is training for a 10K race. For some of her training runs, she records the Regression finds the straight line that comes as close to the points as possible, so it should not be surprising that correlation and regression are related. One of the ways the goodness of fit of a regression line can be measured is by R 2. For the simple two-variable case, R 2 is simply the correlation coefficient r, squared.
