05) based on the normal approximation
to a two-tailed Mann-Whitney test.
The simulations used in this paper clearly show that the thumb rule of 'n [greater than or equal to] 30' for the CLT to provide a good normal approximation
to the probability distribution of the sample mean does not work in the case of a heavily skewed probability distribution such as a typical slot game, and that the normal approximation
is valid even for moderate sample sizes when the game has a symmetric probability distribution of payouts (e.
Chatterjee  provides a rate of normal approximation

A hexagonal field of variation was calculated by means of normal approximation
including arithmetic means, standard deviations, and upper or lower confidence limits ([C.
i] is the normal approximation
to the reported F-test from the ith study, and a measure of the parameter variability on a common scale.
We can compute the normal approximation
of this binomial probability by solving for E(r) and [[sigma].
For the Wilcoxon Signed-Rank test, the normal approximation
Therefore more than one third had values of the denominator that were too small for the normal approximation
to be adequate.

The normal approximation
used in phenotypic distributions of body size may not be appropriate.
