This situation is unusual; if you are in any doubt then use a two sided P value. The term significance level (alpha) is used to refer to a pre-chosen probability and the term P value is used to indicate a probability that you calculate after a given study.
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).
