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 \(r\) measures the strength and direction of a linear relationship. The value of \(r\) ranges from \(- 1\) to \(1\). A positive \(r\) - value (\(0.29>0\)) indicates a positive correlation. The closer \(r\) is to \(0\) (in absolute value), the weaker the correlation. Since \(|0.29|\) is not close to \(1\), it is a weak correlation.

Answer:

a weak positive correlation
