Question

which best describes the strength of the model with an r - value of - 0.93?
a weak positive correlation
a strong positive correlation
a weak negative correlation
a strong negative correlation

Explanation:

The correlation coefficient $r$ ranges from -1 to 1. Values close to -1 or 1 indicate a strong correlation. A negative $r$-value means negative correlation. Since $r = - 0.93$ is close to -1, it is a strong negative correlation.

Answer:

a strong negative correlation
