Small p value means reject null hypothesis
WebLet's return finally to the question of whether we reject or fail to reject the null hypothesis. If our statistical analysis shows that the significance level is below the cut-off value we have set (e.g., either 0.05 or 0.01), we reject the null hypothesis and accept the alternative hypothesis. Alternatively, if the significance level is above ... WebLet's return finally to the question of whether we reject or fail to reject the null hypothesis.

WebSep 1, 2024 · The simplest way to understand hypothesis testing (NHST) — at least for me — is to keep in mind that p-values are probabilities about the data (not about the null and alternative hypotheses): Large p-value means that the data is consistent with the null hypothesis, small p-value means that the data is inconsistent with the null hypothesis. granite group north haven ctWebNov 13, 2024 · One of the most commonly used p-value is 0.05.
