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. A positive \(r\) value indicates a positive correlation. The closer \(r\) is to \(1\) (for positive) or \(- 1\) (for negative), the stronger the correlation. Since \(0.29\) is positive and not close to \(1\), it represents a weak positive correlation.

Answer:

a weak positive correlation
