Question

A researcher believes that an extroverted personality is positively related to self-esteem.She obtains measures of both variables for 25 people,and calculates a correlation coefficient of .35.If the alpha level is .05,directional test,how would this result be reported in a psychological journal?
A)r(25)= .35,p < .05
B)r(24)= .35,p < .05
C)r(23)= .35,p > .05
D)r(23)= .35,p < .05

Quizplus · Accepted Answer

The best choice is D because it correctly reports the correlation coefficient and indicates that the result is significant at an alpha level of .05. The degrees of freedom are adjusted since this is a directional test, so the sample size (n) is reduced by 1 to 24. Therefore, the correct notation is r(23)= .35, p < .05.
