The idea of significance tests Simple hypothesis testing CCSS.Math: HSS.IC.A.2 The third step is to compute the test statistic. To establish these two hypotheses, one is required to study data samples, find a plausible pattern among the samples, and pen down a statistical hypothesis that they wish to test. That is, the test statistic tells us, if H0 is true, how likely it is that we would obtain the given sample result.
