Question

Quizplus · Accepted Answer

Correlation is measured using the correlation coefficient, which ranges from -1 (perfect negative correlation) to +1 (perfect positive correlation), with 0 indicating no correlation. Therefore, the correlation of two variables is between -1 and +1, inclusive. The correlation coefficient ranges between -1 to +1, inclusive. Therefore, option D is the correct choice. The correlation coefficient value of -1 indicates a perfect negative correlation, a value of 0 indicates no correlation and a value of +1 indicates a perfect positive correlation. The correlation coefficient cannot exceed +1 or go below -1.
