excel2007正態分布怎么制作
在學習工作中總會有一些用到正態分布曲線圖的地方，對于不常用Excel的朋友或許不太熟悉吧，今天，學習啦小編就教大家在Excel2007中制作正態分布曲線圖的方法。
Excel2007生成正態分布曲線圖的制作方法
獲取正態分布概念密度。
正態分布概率密度正態分布函數“NORMDIST”獲取。
在這里是以分組邊界值為“X”來計算：
Mean=AVERAGE(A:A)(數據算術平均)
Standard_dev=STDEV(A:A)(數據的標準方差)
Cumulative=0(概率密度函數)
向下填充。
在直方圖中增加正態分布曲線圖。
1、在直方圖內右鍵→選擇數據→添加→
2、系列名稱：選中H1單元格。
3、系列值：選中H2:H21。
4、確定、確定。
修整圖形。
1、在圖表區柱形較下方選中正態分布曲線數據，(正態分布密度值和頻率數值相比太小了，實在看不清，多試幾次，選中后如圖，同時正態分布曲線那數數據處于選中狀態)。
2、右鍵→設置數據列格式→系列繪制在→次坐標軸;
關閉，如圖。
更改系列圖表類型。
1、選中正態分布柱形圖→右鍵→更改系列圖表類型。
2、選中“拆線圖”。
3、確定。
平滑正態分布圖。
選中正態分布曲線→右鍵→設置數據列格式→線型→勾選“平滑線”→關閉。
大功告成!!!
