Question

Quizplus · Accepted Answer

The magnitude of the correlation coefficient, also known as r, indicates the degree to which a linear relationship is approximated between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 0 indicates no linear relationship, and 1 indicates a perfect positive linear relationship. The closer the absolute value of r is to 1, the stronger the linear relationship is between the variables.
