D) -5.00 and 5.00

Question

Quizplus · Accepted Answer

The correlation coefficient, also known as Pearson's r, varies between -1.00 and 1.00. A perfect positive correlation is represented by a correlation coefficient of 1.00, while a perfect negative correlation is represented by -1.00. A correlation coefficient of 0.00 indicates no correlation between the variables. Any value between -1.00 and 1.00 represents varying degrees of correlation. Therefore, option B is the correct answer as it provides the correct range for correlation coefficients.
