WebHere are four points to try it with that make the calculation not too bad: Put these in the formula and you should get r = 0.891, a quite high correlation. Conversely, pick any four points that make a horizontal rectangle, for example (2, 2), (8, 2), (2, 6), (8, 6). If you calculate r for these points, it will be 0. WebThe most common way to calculate the correlation coefficient (r) is by using technology, but using the formula can help us understand how r measures the direction and strength of the linear association between two quantitative variables.
