Question

Quizplus · Accepted Answer

The critical value for a correlation coefficient (r) depends on the sample size and the desired level of significance. For a sample size of 125 and a significance level of .05 (two-tailed), the critical value is approximately ± .195. This can be found in statistical tables or calculated using statistical software, based on the degrees of freedom (n-2) for the correlation test.
