Quizplus · Accepted Answer

The correlation coefficient measures the strength and direction of the linear relationship between two variables. It ranges from -1 (perfect negative correlation) to 1 (perfect positive correlation), with 0 indicating no correlation. The other options (covariance, standard deviation, and variance) are measures of variability or spread, but do not directly indicate the strength of the relationship between two variables.
