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 \(r -\)value (correlation coefficient) ranges from \(- 1\) to \(1\). A positive \(r -\)value (\(0.29>0\)) indicates a positive correlation. The closer \(r\) is to \(0\), the weaker the correlation. Since \(0.29\) is not close to \(1\) (strong positive) or \(-1\) (negative), it's a weak positive correlation.

Answer:

a weak positive correlation
