A scatter graph is a two-dimensional plot of points that shows the degree of association or correlation between two variables. Each point represents the paired measurements of the two variables. The degree of correlation referred to as the correlation coefficient can range from -1.0 to +1.0 inclusive. The sign of the coefficient indicates the direction of the relationship; the absolute value of the coefficient indicates the magnitude of the relationship. This scatter graph displays the degree of association or correlation between grade point average and the number of videos watched by students each week.
