论文部分内容阅读
一、内容和内容解析“两个变量的线性相关”是高中数学必修③统计知识部分的最后一个内容,也可以说是统计知识在这一阶段的归宿.“统计”这一章前两节主要学习了如何科学的收集数据,并根据收集的样本数据的数字特征去估计总体的数字特征.所收集的样本数据是否可以发挥更大的威力呢?这就自然的涉及到变量分析最基本的方法——回归分析.“两个变量的线性相关”大约需要4个课时.本节
First, the content and content analysis “The linear correlation of two variables ” is the last content of high school mathematics compulsory ’s statistical knowledge part, also can say that the statistical knowledge in this stage the fate “statistics ” this chapter The first two sections mainly study how to collect the data scientifically and estimate the overall digital characteristics according to the digital characteristics of the collected sample data.Is it possible to collect the sample data to exert more power? This naturally involves variable analysis The most basic method - Regression Analysis. “The” Linear Correlation of Two Variables "takes about 4 hours.
