2-tailed student's t-test翻译成中文是什么检验?

The two-tailed test is a statistical test used in inference,in which a given statistical hypothesis will be rejected when the value of the statistic is either sufficiently small or sufficiently large.The test is named after the "tail" of data under the far left and far right of a bell-shaped normal data distribution,or bell curve.However,the terminology is extended to tests relating to distributions other than normal.
