WebAug 10, 2024 · The p -value is a number between 0 and 1 and interpreted in the following way: A small p -value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p -value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.
