Which value of r indicates a stronger correlation: r=0.844 or r= -0.867? Explain your reasoning. Choose the correct answer below. O A. r= -0.867 represents a stronger correlation because | -0.867| > |0.844. B. r=0.844 represents a stronger correlation because 0.844> -0.867. OC. r=0.844 represents a stronger correlation because | -0.867| > |0.844|. D. r= -0.867 represents a stronger correlation because 0.844 > -0.867.
