Use this module to make a scatter plot of one variable against another through all patterns. The module computes the linear correlation coefficient between two variables.
The linear correlation coefficient is a statistical measure of the strength of the relationship between the two characteristics that are graphed in the scatter plot. The r coefficient can range from 1 to +1 . The closer r is to 1, the stronger the positive linear relationship, and the closer r is to 1, the stronger the negative linear relationship. When r is near 0 there is no linear relationship.
