WebThe first step is to run the correlation analyses between the two independent groups and determine their correlation coefficients ( r); any negative signs can be ignored. The next step is to note, or write down, the sample sizes per each independent group. Then, using a statistical chart with z values and calculator, or an online calculator ... http://psychmike.com/dependent_correlations.php

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.

WebMar 5, 2016 · It is not applicable to the paired samples t-test. Also, Fisher's r-to-z transformation is for Pearson product-moment correlations, not point biserial correlations, so the 1/(n−3) equation for the variance does not apply, regardless of what value for n you plug into it.

WebAdd a comment. 1. Not sure whether a Fisher's z transform is appropriate here. For H 0: ρ = 0 (NB: null hypothesis is for population ρ, not sample r ), the sampling distribution of the correlation coefficient is already symmetric, so no need to reduce skewness, which is what Fisher's z aims to do, and you can use Student's t approximation.
