excel频数分布表制作的方法总结
spss频数分布表怎么设置组距？
spss频数分布表怎么设置组距？
不用设置组距，
你可以自己重建一个设置自己想要的数据文件，之后就可以进行一定组距的频数分布图
频数分布表计算法？
1.
频数表输出是分类变量统计分析的基本内容,首先准备好进行频数分析的数据。
2.
然后依次点击“分析”,“描述统计”,“频率”,弹出频率窗口。
3.
在频率窗口中,将年龄,性别和Q1,Q9选入“变量”框,点击“statistics”,...
4.
频数分布表就做好了,每个变量会给一个表,比较简单,就不做详细解释了。
Excel怎样画对数正太分布的图？
一、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：
MeanAVERAGE(A:A)(数据算术平均）
Standard_devSTDEV(A:A)(数据的标准方差）
Cumulative0(概率密度函数）
二、向下填充。
三、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。
四、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。
五、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。
六、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！！！
