对于高中数学教学过程中,如何运用“线性回归直线”的教学模式对高中数学进行分析研究,是每一个高中数学老师必须面对的问题,而且也是学生们不容易掌握的问题。而这方面对于直线高中生学习有一定的参考和指导作用。基于此种情况,本文分析研究组数据描绘成散点图,然后用一条斜向下的直线去分割数量得到的直线肯定不合适所以我们还是用和数据走势一致的直线去拟合回归直线,同时也很容易想到这样的直线不定。文中通过对三种方式拟合回归直线的分析与讨论,最后进行了总结评论。
In the process of high school mathematics teaching, how to use the teaching mode of “Linear Regression Straight Line” to analyze high school mathematics is a problem every high school mathematics teacher must face, and it is also a problem that students can not easily grasp. In this regard, there is a certain reference and guidance for the learning of high school students. Based on this situation, we analyze the data of the research group as a scatter plot, and then use a diagonal straight line to divide the number to get a straight line which is definitely not suitable. Therefore, we use the same line with the data trend to fit the regression line, meanwhile It is also easy to think of such a straight line. Through the analysis and discussion of fitting three regression lines in the three ways, the article concludes with comments.
