Quizplus · Accepted Answer

The correlation coefficient measures the strength of the relationship between two variables, but it does not imply causality. It also shows the direction and degree of association between the two variables, ranging from -1 to 1, where a value of 0 indicates no correlation. The variance and range are measures of dispersion and have no direct relationship to the correlation coefficient.
