Statistical hypothesis test
open-in-new
<p>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 <a href="/facts/Test_statistic/IBwfN5Kx">test statistic</a>. Then a decision is made, either by comparing the test statistic to a <a href="/facts/Critical_value_(statistics)/yv9RPF6U">critical value</a> or equivalently by evaluating a <a href="/facts/P-value/InnYd1bz"><i>p</i>-value</a> computed from the test statistic. </p>
