Quizplus · Accepted Answer

A correlation coefficient close to zero indicates a weak relationship between two variables. A correlation coefficient of minus one (-1) indicates a strong negative relationship, and a correlation coefficient that is statistically significant may or may not indicate a strong or weak relationship. The fact that a correlation coefficient doesn't prove a causal relationship between variables is important to keep in mind, but it doesn't help the student remember what kind of coefficient shows a weak relationship.
