excel2007生成正態分布曲線圖的方法

　　在學習工作中總會有一些用到正態分布曲線圖的地方，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步驟如下：

　　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!!!

　　本例中原始數據：
