Quizplus · Accepted Answer

The correlation coefficient is a measure of the strength and direction of the linear relationship between two variables. It can range from -1 to +1, where a value of -1 suggests a perfect negative linear relationship, 0 suggests no linear relationship, and +1 suggests a perfect positive linear relationship. Hence, the best choice is C, as it includes the full range of possible values for the correlation coefficient.
