對(duì)于檢驗(yàn)統(tǒng)計(jì)量的定義:
A test statistic is a quantity, calculated using a sample, whose value is the basis for deciding whether to reject or not reject the null hypothesis.
We compare the computed value of the test statistic to a critical value for the same test statistic to determine whether to reject or not reject the null hypothesis.
