Question

which r - value suggests a weak positive correlation?
a. r = - 0.23684
b. r = 0.23684
c. r = - 0.97917
d. r = 0.97917

Explanation:

• The correlation coefficient \(r\) ranges from \(- 1\) to \(1\).
• A positive correlation has \(r>0\), and a negative correlation has \(r < 0\).
• The closer \(|r|\) is to \(1\), the stronger the correlation. The closer \(|r|\) is to \(0\), the weaker the correlation.
• For a weak positive correlation, we need \(r>0\) and \(|r|\) close to \(0\).

Answer:

B. \(r = 0.23684\)
