This function tests the null hypothesis that the skewness of the population that the sample was drawn from is the same as that of a corresponding normal distribution.

Parameters:

a : array

The data to be tested

axis : int or None, optional

Axis along which statistics are calculated. Default is 0. If None, compute over the whole array a.

Returns:

z-score : float

The computed z-score for this test.

p-value : float

a 2-sided p-value for the hypothesis test

Notes

The sample size must be at least 8.
