A) 0.8
B) -0.9

D) -1.3
E) 1

Question

Quizplus · Accepted Answer

A correlation coefficient of -0.9 indicates a strong negative linear relationship between the two variables. The closer the coefficient is to -1, the stronger the negative relationship. A coefficient of 0 indicates no relationship and a coefficient of 1 indicates a strong positive relationship. A coefficient of 0.8 indicates a strong positive relationship, a coefficient of 0.9 indicates a very strong positive relationship, and a coefficient of -1.3 is not possible as the values range from -1 to 1.
