A '''statistical hypothesis test''' is a method of statistical inference used to decide whether the data provide sufficient evidence to reject a particular hypothesis. A statistical hypothesis test typically involves a calculation of a [[test statistic]]. Then a decision is made, either by comparing the test statistic to a [[Critical value (statistics)|critical value]] or equivalently by evaluating a [[p-value|''p''-value]] computed from the test statistic. Roughly 100 [[list of statistical tests|specialized statistical tests]] are in use and noteworthy.<ref>{{cite book |last1=Lewis |first1=Nancy D. |last2=Lewis |first2=Nigel Da Costa |last3=Lewis |first3=N.
