In the following example we are passing the quarter variable to the groups argument to group the months by quarter. dotchart(sold, pch = 19, pt.cex = 1.5, labels = month, groups = rev(quarter)) Matrix as input 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.
