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. WebThe Fisher transformation is an approximate variance-stabilizing transformation for r when X and Y follow a bivariate normal distribution. This means that the variance of z is … fish gills exchange surfaces
