1教材分析1.1内容分析在人教A版《数学3》(必修)学习了收集、整理数据,了解了用样本估计总体特征的思想,并懂得了如何用最小二乘法求两个线性相关变量的回归直线的方法。编者的意图是,在本节课通过典型案例(人的体重与身高的关系),探究在实际问题中较系统地经历数据分析的过程,培养学生对数据的直观感觉,进一步认识统计方法的特点,体会统计方法应用的广泛性。
1 textbook analysis 1.1 Content Analysis In People’s Education A version of “Mathematics 3” (compulsory) to learn to collect, organize data, understand the use of samples to estimate the overall characteristics of the idea, and know how to use the least squares method for two linearly related variables Regression straight line method. The intent of the editor is to explore the process of data analysis more systematically in practical problems through the typical case (the relationship between body weight and height) in this lesson, to develop students’ visual perception of the data and to further understand the characteristics of statistical methods , Experience the extensive application of statistical methods.
