P-Value

The p-value is associated with a test statistic; the p-value measures consistency between the results actually obtained in the trial and the explanation for those results, e.g., a p-value of 0.002 favoring group A arises very infrequently when the only differences between groups A and C are due to chance, chance alone would produce such a result only twice in every thousand studies (Alliance Terminology & Data Resources May 2021)
