Question

Quizplus · Accepted Answer

The correlation coefficient is a numerical value that measures the strength and direction of the linear relationship between two variables. A value of 0.0 indicates no correlation, while a value of 1.0 or -1.0 indicates a perfect positive or negative correlation, respectively. Choice A, 0.0, indicates no correlation. Choice B, 1.5, is not a possible value for a correlation coefficient since it must fall between -1.0 and 1.0. Choice C, 0.65, indicates a moderate positive correlation, but choice D, -0.72, indicates a strong negative correlation, making it the strongest correlation coefficient among the choices given.
