The following are coefficients of correlation (r). The one that indicates a strong positive linear relationship between the two variables of interest is:
A) 0.8
B) -0.9
C) 0.9
D) -1.3
E) -1

Question

Quizplus · Accepted Answer

A correlation coefficient of 0.9 indicates a strong positive linear relationship between the two variables. A coefficient of 0.8 also indicates a strong positive relationship, but not as strong as 0.9. Coefficients of -0.9, -1.3, and -1 indicate negative relationships. A coefficient cannot be greater than 1 in magnitude, so -1.3 and -1 are not valid correlation coefficients.
