As you know, the Student t-test can be used only to compare two groups. When you have k groups you can't use a t-test for each couple because, if you have fixed alpha=0.05 for each t-test, there is a probability of k*0.05 to find a difference when it isn't (Bonferroni inequality).
The Holm-Sidak test is a step-down "recursive reject", because it applies an accept/reject criterion on a sorted set of null hypothesis, starting from the lower p-value and going up to the acceptance of null hypothesis.
For each comparison, the alpha value is set according to Sidak correction of Bonferroni inequality.
针对多组检验。一般用matlab做。
要做配对T检验可以在spss中依次选择：分析->比较均值->配对样本T检验
