Question

which best describes the strength of a model with an r - value of 0.29?
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. A positive $r$ - value indicates a positive correlation. Values close to 0 imply a weak correlation. Since $r = 0.29$ is positive and close to 0, it represents a weak positive correlation.

Answer:

a weak positive correlation
