Question

19 which r-value suggests a weak positive correlation?
a) $r = 0.17454$
b) $r = -0.17454$
c) $r = 0.98264$
d) $r = -0.98264$

Explanation:

The correlation coefficient \(r\) ranges from -1 to 1. A positive \(r\) indicates a positive correlation, and values close to 0 indicate a weak correlation.

• Option B and D have negative \(r\), so they represent negative correlations.
• Option C has an \(r\) very close to 1, indicating a strong positive correlation.
• Option A has a positive \(r\) close to 0, indicating a weak positive correlation.

Answer:

A. \( r = 0.17454 \)
