Webthe raw data. In other words, the Fisher z' method does not alter the original scale of measurement for X or Y. Nonnormality A key assumption of the Fisher z' confidence interval method is that X and Y have a bivariate normal distribution in the pop-ulation. When this assumption is met, the Fisher z' method is WebX and X̅ are standardised slightly differently. In both cases, the denominator is the square root of the variance, like so: For X, Z = (X-μ) / σ. For X̅, Z = (X̅ - μ) / (σ / √n) This fits with what we know about the central limit theorem. For X, the variance is σ².
