Quizplus · Accepted Answer

The correlation coefficient is a statistic that describes how strongly variables are related to one another. It ranges from -1 to +1, with values closer to -1 indicating a strong negative relationship and values closer to +1 indicating a strong positive relationship. A value of 0 indicates no relationship. The correlation coefficient does not measure spread, central tendency, or variability.
