Feb 12, 2024 at 15:46 $\begingroup$ The problem is I get different p-value using fisher transformation and t-distribution. For example in the wikipedia xample, rho=-0.1757 and p-value=0.62. Using Fisher transformation. WebThe z-score allows you to compare data from different samples because z-scores are in terms of standard deviations. A positive z-score means the data value is higher than average. A negative z-score means it's lower than average. You can also determine the percentage of the population that lies above or below any z-score using a z-score table. how to start shadowlands 2022 https://ctemple.org
