Why a small pvalue is gotten
Everyone knows, definitively, against the Psychologists thought all people is wrongly persuaded, that the pvalue is not the probability the Null Hypothesis is ´true´ (if this was even to be really stated in inference subjected to randomness). However what is clear enough is that a low probability event occurs rarely and if so, consequentially, though it is present to the researcher is symptomatic that this supposed oddness is very unlike. So unlike that, rationally, should be definitively discarded. This is what happens with a Hypothesis with very low pvalue. However running the risk to be wrong: Type I error which probability was coined alpha. Because the matter concerns likeliness, never true/false, we are indisputably gambling between evidence and reality. As always, I add.
