Question

choose all values of the correlation coefficient, r, that indicate a strong but not perfect linear relationship between variables.
a. r = - 0.85
b. r = - 0.10
c. r = 0.15
d. r = 0.90
e. r = 1.00

Explanation:

The correlation coefficient \(r\) ranges from - 1 to 1. Values close to - 1 or 1 indicate a strong linear relationship. Values close to 0 indicate a weak linear relationship. A strong (but not perfect) linear relationship is indicated by \(r\) values that are close to - 1 or 1 but not exactly - 1 or 1. So, \(r=-0.85\) and \(r = 0.90\) indicate strong (but not perfect) linear relationships.

Answer:

B. \(r=-0.85\), D. \(r = 0.90\)
