Question

Suppose you perform a two-tailed significance test on a correlation using 29 participants.Your  is 0.56,which is a significant correlation coefficient.Which of the following is the correct way to report this finding?
A)r(29)= 0.56,p < 0.05 
B)r(28)= 0.56,p < 0.05 
C)r(27)= 0.56,p > 0.05 
D)r(27)= 0.56,p < 0.05

Quizplus · Accepted Answer

The correct formula for determining the degrees of freedom when conducting a significance test on a correlation coefficient is df=n-2, where n is the sample size. In this case, the sample size is 29, so the degrees of freedom are 29-2=27. Additionally, the correlation coefficient is reported as r=0.56, which is significant at the p<0.05 level. Therefore, the correct way to report this finding is D: r(27)=0.56, p<0.05.
