WebApr 21, 2013 · All a p-value of 0.05 means is there’s a 95% chance that the hypothesis was indeed working. A p-value of 0.051 means there was a 94.9% of the hypothesis was working. I agree that if one prespecifies 0.05 as the threshold then, yes, the p-value of 0.051 is not significant. But is to say it was “almost significant” such a travesty?
