高中数学中包括了统计学方差的知识,由于学生在初中阶段已经对于这部分知识有了基本的认识,因此高中教师针对这部分内容教学相对容易一些。本文主要介绍了高中数学中统计学方差的性质,并总结出了方差性质对于解决问题的作用,希望可以为相关教师和学生提供参考。 High school mathematics includes statistical variance of knowledge, as students have already had a basic understanding of this part of the knowledge in the junior high school stage, so high school teachers teaching for this part of the content relatively easy. This paper mainly introduces the nature of statistical variance in high school mathematics and summarizes the role of the nature of variance in solving the problem. I hope it can provide references for teachers and students concerned.
