In statistics, a standard normal table, also called the unit normal table or Z table, [1] is a mathematical table for the values of Φ, the cumulative distribution function of the normal distribution.

The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance.
Fisher's z-distribution is the statistical distribution of half the logarithm of an F -distribution variate: It was first described by Ronald Fisher in a paper delivered at the International Mathematical Congress of 1924 in Toronto. [1] . Nowadays one usually uses the F -distribution instead.
Rozkład normalny, rozkład Gaussa (w literaturze francuskiej zwany rozkładem Laplace’a-Gaussa) – jeden z najważniejszych rozkładów prawdopodobieństwa, odgrywający ważną rolę w statystyce. Wykres funkcji prawdopodobieństwa tego rozkładu jest krzywą w kształcie dzwonu (tak zwaną krzywą dzwonową).
5 lis 2020 · The standard normal distribution, also called the z-distribution, is a special normal distribution where the mean is 0 and the standard deviation is 1. Any normal distribution can be standardized by converting its values into z scores.
24 lut 2022 · Along with the Fisher $ F $-distribution, known as the distribution of the dispersion proportion, the Fisher $ z $-distribution was originally introduced in the analysis of variance by R.A. Fisher (1924). His intention was that the $ z $-distribution should be the basic distribution for testing statistical hypotheses in the analysis of variance.
z-Score: definition, formula, calculation & interpretation. This tutorial is about z-standardization (z-transformation). We will discuss what the z-score is, how z-standardization works, and what the standard normal distribution is. In addition, the z-score table is discussed and what it's used for.
