A researcher uses a Pearson product moment correlation to analyze the association between two continuous variables. He found that r = .13, p = .03. These results indicate:
A) A nonsignificant relation between the two variables
B) A good prediction of the dependent variable from the independent variable
C) A statistically significant but weak positive relation between the two variables
D) A large effect size

Question

Quizplus · Accepted Answer

The correlation coefficient r = .13 indicates a weak positive association, while p = .03 indicates that the association between the two variables is statistically significant. Therefore, the answer is option C, which states that there is a statistically significant but weak positive relation between the two variables.
