excel2007生成正态分布曲线图的方法

学习啦在线学习网 　　在学习工作中总会有一些用到正态分布曲线图的地方，今天，学习啦小编就教大家在Excel2007中制作正态分布曲线图的方法。

　　Excel2007生成正态分布曲线图的步骤如下：

　　获取正态分布概念密度。

　　正态分布概率密度正态分布函数“NORMDIST”获取。

　　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。

　　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!!!
