"WebCompute a p-value: this is the probability of seeing the observed effect amongst the null data, in other words, by chance. We do this through repeated simulation of the null data. In our case, we shuffle the ‘date’ labels of the data many times and simply count the occurrence of our test statistic as it appears through multiple simulations. " - Detecting p-hacking
