All hypothesis tests ultimately use a p-value to weigh the strength of the evidence (what the data are telling you about the population). The p-value is a number between 0 and 1 and interpreted in the following way: A small p-value (typically â¤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis.
P value as posterior probability of the truth of the null hypothesis is false and not even close. to valid under any reasonable model, yet this misunderstanding persists even in high-stakes. settings (as discussed, for example, by Greenland in 2011).2 The formal view of the P value. as a probability conditional on the null is mathematically correct but typically irrelevant to. research goals (hence, the popularity of alternativeâif wrongâinterpretations).
