The number of tails:We need to know whether our t-test is one-tailed or two-tailed because we will use the respective one-tail or two-tail row to mark the alpha level. The alpha levels are listed at top of the table (0.50, 0.25, 0.20, 0.15…for the one-tail and 1.00, 0.50, 0....

T-test 可能是假设检验（概率论与数理统计）里面的t 分布。one-Tailed t-Test 单边t分布（就是分布图的一侧，一般都是正侧） 。two就是双边 简单说一下one-tailed test（单边检测）和two-tailed test（双边检测）。分别适用于单因素方差分析（one-way ANOVA）和双因素方差分析（two-way ANOVA）。...
使用单侧或双侧是由spss 自动指定，这个你是不能改动的。但是，你可以通过调整双侧检验的显著水平来达到进行单侧检验的目的。例如，如果你想进行a=0.05的单侧检验，你可以设定双侧检验的a=0.10，这就相当于单侧检验的a=0.05；如果你想进行a=0.01的单侧检验，你可以设定双侧检验的a=0.02，这就...
