Source

Do baseline P-values follow a uniform distribution in randomised trials?

Embedded

yes

Text

The basic simulation generated two groups of 10 observations from a Standard Normal distribution. The two sample t test was used to test the true null hypothesis that the means were the same in the two populations. This was repeated 10,000 times and the distribution of the resulting P-values displayed as a histogram.
