Quizplus · Accepted Answer

The correlation coefficient measures the strength and direction of a linear relationship between two variables on a scatterplot. The value 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 strength of the relationship is determined by the absolute value of the correlation coefficient, regardless of the sign. Therefore, -0.84 (B) indicates the strongest relationship because its absolute value (0.84) is the highest among the options.
