excel正态分布曲线图 excel2021生成正态分布曲线图的方法

1、本文格式为word版，下载可任意编辑excel正态分布曲线图 excel2021生成正态分布曲线图的方法 在学习工作中总会有一些用到正态分布曲线图的地方，今日，我就教大家在excel2021中制作正态分布曲线图的方法。 excel2021生成正态分布曲线图的步骤如下： 猎取正态分布概念密度。 正态分布概率密度正态分布函数"normdist'猎取。 在这里是以分组边界值为"x'来计算： mean=average(a:a)(数据算术平均) standard_dev=stdev(a:a)(数据的标准方差) cumulative=0(概率密度函数) 向下填充。 在直

2、方图中增加正态分布曲线图。 1、在直方图内右键选择数据添加 2、系列名称：选中h1单元格。 3、系列值：选中h2:h21。 4、确定、确定。 修整图形。 1、在图表区柱形较下方选中正态分布曲线数据，(正态分布密度值和频率数值相比太小了，实在看不清，多试几次，选中后如图，同时正态分布曲线那数数据处于选中状态)。 2、右键设置数据列格式系列绘制在次坐标轴; 关闭，如图。 更改系列图表类型。 1、选中正态分布柱形图右键更改系列图表类型。 2、选中"拆线图'。 3、确定。 平滑正态分布图。 选中正态分布曲线右键设置数据列格式线型勾选"平滑线'关闭。 大功告成! 本例
