    A desired significance level α would then define a corresponding "rejection region" (bounded by certain "critical values"), a set of values t is unlikely to take if was correct. If we reject H 0 {\displaystyle H_{0}} in favor of H 1 {\displaystyle H_{1}} only when the sample t takes those values, we would be able to keep the probability of ...

    Although the 30 samples were all simulated under the null, one of the resulting p-values is small enough to produce a false rejection at the typical level 0.05 in the absence of correction. Multiple comparisons arise when a statistical analysis involves multiple simultaneous statistical tests, each of which has a potential to produce a "discovery".
