educ.jmu.eduiii. The correlation coefficient is bound by –1 and +1. The closer the coefficient to –1 or +1, the stronger is the correlation. iv. With the exception of the extremes (that is, r = 1.0 or r = -1), we cannot really talk about the strength of a relationship indicated by the correlation coefficient without a statistical test of significance. v.

courses.aiu.eduProduct Moment Correlation Coefficient, to test if there is a linear relationship between the variables. To quantify the strength of the relationship, we can calculate the correlation coefficient (r). Its numerical value ranges from +1.0 to -1.0. r > 0 indicates positive linear relationship, r < 0
Correlation Between Continuous & Categorical Variables
