If the points are roughly enclosed by a circle, then there is no correlation. Strong or Weak? Hint: To visualize this, enclose the plotted points in an oval. If the oval is thin, then the correlation is strong. If the oval is fat, then the correlation is weak.

This is an artifact of the way axes have been scaled—the large amount of space between points in the left-hand plot makes it appear to have a less strong correlation. The eye is not a good judge of correlational strength—we need an objective way to make this type of assessment.

Besides describing correlation as “strong” or “weak”, it is also described numerically using what is known as the correlation coefficient. The correlation coefficient (symbolically represented by r) is a number between 1 and -1. The closer to 1 or -1 the better the fit, the stronger the correlation. The closer to 0 the weaker the fit ...
