Correlation coefficient is a measure of the degree of the linear relationship between two variables. It varies between -1.00 and +1.00, where -1.00 indicates a perfect negative correlation, 0 indicates no correlation, and +1.00 indicates a perfect positive correlation. Therefore, the correct range is -1.00 to +1.00.
