Significance test for correlation coefficient
WebThis calculator will determine whether two correlation coefficients are significantly different from each other, given the two correlation coefficients and their associated sample sizes. Values returned from the calculator include the probability value and the z-score for the significance test. A probability value of less than 0.05 indicates that the two correlation … WebResults. When the P-value is less than 0.05, the conclusion is that the two coefficients are significantly different. In the example a correlation coefficient of 0.86 (sample size = 42) is compared with a correlation coefficient of 0.62 (sample size = 42). The resulting z-statistic is 2.5097, which is associated with a P-value of 0.0121.
