https://education.arcus.chop.edu/null-hypothesis-testing/
WEBNull Hypothesis Significance Testing (NHST) is a common statistical test to see if your research findings are statistically interesting. Its usefulness is sometimes challenged, particularly because NHST relies on p values, which are sporadically under fire from statisticians. The important thing to remember is not the latest p-value-related salvo in …

WEBApr 22, 2022 · 1. INTRODUCTION. Traditional null hypothesis significance testing (NHST), incorporating the null hypothesis and two‐sided alternative, p value, plus critical level of significance of 0.05 needs little introduction. Statistical significance (p < 0.05) underpins decision‐making in medicine, and none less so than in obstetric and gynecological …

WEBHypothesis testing is “a wrongheaded view about what constitutes scientific progress” (Luce, 1988) NHST is also widely misunderstood, largely because it violates our intuitions about how statistical hypothesis testing should work. Let’s look at an example to see. This page titled 16.1: Null Hypothesis Statistical Testing (NHST) is shared ...

WEB16.3.5 Step 5: Determine the probability of the data under the null hypothesis. This is the step where NHST starts to violate our intuition – rather than determining the likelihood that the null hypothesis is true given the data, we instead determine the likelihood of the data under the null hypothesis - because we started out by assuming that the null hypothesis …
