在学习工作中总会有一些用到直方图、正态分布曲线图的地方,下面手把手教大家在Excel2007中制作直方图和正态分布曲线图

用Excel2007制作直方图和正态分布曲线图

工具/原料

  • Excel(2007)

方法/步骤

  1. 1

    数据录入

    新建Excel文档,录入待分析数据(本例中将数据录入A列,则在后面引用中所有的数据记为A:A);

  2. 2

    计算“最大值”、“最小值”、“极差”、“分组数”、“分组组距”,公式如图:

  3. 3

    分组

    “分组”就是确定直方图的横轴坐标起止范围和每个小组的起止位置。选一个比最小值小的一个恰当的值作为第一个组的起始坐标,然后依次加上“分组组距”,直到最后一个数据值比“最大值”大为止。这时的实际分组数量可能与计算的“分组数”有一点正常的差别。类似如下图。

    统计频率

    “频率”就是去统计每个分组中所包含的数据的个数。

    最简单的方法就是直接在所有的数据中直接去统计,但当数据量很大的时候,这种方法不但费时,而且容易出错。

    一般来说有两种方法来统计每个小组的数据个数:1.采用“FREQUENCY”函数;2.采用“COUNT IF”让后再去相减。

    这里介绍的是“FREQUENCY”函数方法:

    “Date_array”:是选取要统计的数据源,就是选择原始数据的范围;

    “Bins_array”:是选取直方图分组的数据源,就是选择分组数据的范围;

    生成“FREQUENCY”函数公式组,步骤如下:

    1. 先选中将要统计直方图每个子组中数据数量的区域

    2. 再按“F2”健,进入到“编辑”状态

    3. 再同时按住“Ctrl”和“Shift”两个键,再按“回车Enter”键,最后三键同时松开,大功告成!

    制作直方图

    选中统计好的直方图每个小组的分布个数的数据源(就是“频率”),用“柱形图”来完成直方图:

    选中频率列下所有数据(G1:G21),插入→柱形图→二维柱形图

    修整柱形图

    选中柱形图中的“柱子”→右键→设置数据系列格式:

    1、系列选项,分类间距设置为0%;

    2、边框颜色:实线,白色(你喜欢的就好)

    3、关闭“设置数据系列格式”窗口

    直方图大功造成!

制作正态分布图

  1. 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)

  2. 向下填充

  3. 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

  4. 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)。

  5. 2、右键→设置数据列格式→系列绘制在→次坐标轴;

    关闭,如图

  6. 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

    用Excel2007制作直方图和正态分布曲线图
  7. 2、选中“拆线图”

    3、确定

  8. 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!!!
