WebIn the SciPy implementation of these tests, you can interpret the p value as follows. p <= alpha: reject H0, not normal. p > alpha: fail to reject H0, normal. This means that, in general, we are seeking results with a larger p-value to confirm that our sample was likely drawn from a Gaussian distribution.
