WebJun 18, 2024 · After this is said, to calculate sample size, you need prior knowledge. Sample size should NEVER be calculated based on the observations used for the actual analysis. An alterative for using fishers exact test for calculating sample size is to use proportions. Second you ask about correction for multiple testing. 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 …

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.
