which correlation coefficient indicates a strong positive correlation?
a. $r=-0.09$
b. $r = - 0.1$
c. $r=+0.5$
d. $r=+0.9$

Explanation:

The correlation coefficient $r$ ranges from - 1 to 1. A positive value of $r$ indicates a positive correlation, and the closer $r$ is to 1, the stronger the positive correlation. Among the given options, +0.9 is closest to 1 among the positive - valued coefficients.

D. $r = +0.9$
