WebAug 10, 2024 · In statistics, when you test a hypothesis about a population, you find a p-value and use your test statistic to decide whether to reject the null hypothesis, H 0. A p-value is a probability associated with your critical value. The critical value depends on the probability you are allowing for a Type I error. WebJun 11, 2024 · P-Values, or probability values, help us understand the statistical significance of a finding. The P-Value is used to test the likely validity of the null hypothesis. If the null hypothesis is considered improbable according to the P-Value, then that leads us to believe that the alternative hypothesis might be true.
