在之前的学习中,我们掌握了单样本t检验。在本章,我们学习了两样本t检验的方法。其中,独立样本t检验是在两样本互不相关的基础上进行的,而相关样本t检验的两样本之间存在匹配或前后比较关系。学会区分并应用这两种t检验方法,有助于我们判断两个样本之间是否存在显著差别。注意学习本章时,可以结合之前单样本t检验的内容进行对比学习。
In previous lectures, we have mastered the single sample T-test. In this chapter, we learned the method of two sample T-test. Among them, the independent sample t-test is conducted on the basis of two samples being uncorrelated, while the correlated sample T-test shows that there is a matching or comparison relationship between the two samples. Learning to distinguish and apply these two t-test methods can help us determine whether there is a significant difference between two samples. When studying this chapter, you can combine the content of the previous single sample t-test for comparative learning.
