| 中文摘要: |
| 本文目的是介绍算术均数以及单组设计、配对设计和成组设计一元定量资料t检验的基本原理及SAS实现。首先对算术均数的概念、适用条件和计算公式进行介绍；其次，介绍不同设计类型t检验的基本原理，结合SAS实例进行分析，并对相关结果进行解释；最后，讨论不同设计类型t检验应用的注意事项。 |
| 英文摘要: |
| The purpose of this article was to introduce the arithmetic mean, as well as the basic principle and SAS implementation of single-group design, paired design and group design unary quantitative data t test. Firstly, the concept of arithmetic mean, applicable conditions and calculation formulas were introduced. Secondly, the basic principles of t tests of different design types were introduced, combined with SAS examples for analysis, and related results were explained. Finally, discuss application considerations for different design types of t test. |
