t检验方法在教学中的应用探讨

Discussion on the Application inTeaching

合理应用统计学的原理,可以对现有的数据分析,进而做出推断,并为教学提供参考。这一过程被称为统计推断。在教学改革的过程中,往往收集了大量的数据后,无法有效进行统计分析。假设检验是一种重要的统计推断技术。本文列举了t假设检验的适用范围、应用方法和使用的注意事项,并以实际案例说明其应用范围和注意事项。

Reasonable application of statistics theory can analyze the existing data, and make inferences, providing a refer- ence for the teaching. This process is called statistical inference. In the process of teaching reform, a lot of data cannot be statistically analyzed after collection. Hypothesis testing is an importantstatistical inference technique. This paper enumera- tes the scope of application of the t hypothesis testing, application methods and precautions. Besides, it demonstrates its scope of application and precautions through actual case.
