WebApr 5, 2024 · Fisher z has a stronger body and is more symmetrical. The horizontal lines indicate the 5%, 50% and 95% quantile. Clearly, the values of Fisher z lie closer together and closer to zero. WebThe result is a z-score which may be compared in a 1-tailed or 2-tailed fashion to the unit normal distribution. By convention, values greater than 1.96 are considered significant if a 2-tailed test is performed. How it's done.
