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. how to tame a shark
