WebA researcher reports the following Pearson correlation coefficient, \( r=.370 \), using a sample of 28 participants. Is the \( p \) value less than .05 for this test? yes, because the critical value is equal to .361 yes, because the critical value is smaller than .361 no, because the critical value is larger than .374 . no, because the critical ... WebFor example, correlations of .60 and -.60 are of equal magnitude, and are both larger than a correlation of .30.
