excel2007正態(tài)分布怎么制作

　　在學(xué)習(xí)工作中總會(huì)有一些用到正態(tài)分布曲線圖的地方，對(duì)于不常用Excel的朋友或許不太熟悉吧，今天，學(xué)習(xí)啦小編就教大家在Excel2007中制作正態(tài)分布曲線圖的方法。

　　Excel2007生成正態(tài)分布曲線圖的制作方法

　　獲取正態(tài)分布概念密度。

　　正態(tài)分布概率密度正態(tài)分布函數(shù)“NORMDIST”獲取。

　　在這里是以分組邊界值為“X”來(lái)計(jì)算：

　　Mean=AVERAGE(A:A)(數(shù)據(jù)算術(shù)平均)

　　Standard_dev=STDEV(A:A)(數(shù)據(jù)的標(biāo)準(zhǔn)方差)

　　Cumulative=0(概率密度函數(shù))

　　向下填充。

　　在直方圖中增加正態(tài)分布曲線圖。

　　1、在直方圖內(nèi)右鍵→選擇數(shù)據(jù)→添加→

　　2、系列名稱(chēng)：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(qū)柱形較下方選中正態(tài)分布曲線數(shù)據(jù)，(正態(tài)分布密度值和頻率數(shù)值相比太小了，實(shí)在看不清，多試幾次，選中后如圖，同時(shí)正態(tài)分布曲線那數(shù)數(shù)據(jù)處于選中狀態(tài))。

　　2、右鍵→設(shè)置數(shù)據(jù)列格式→系列繪制在→次坐標(biāo)軸;

　　關(guān)閉，如圖。

　　更改系列圖表類(lèi)型。

　　1、選中正態(tài)分布柱形圖→右鍵→更改系列圖表類(lèi)型。

　　2、選中“拆線圖”。

　　3、確定。

　　平滑正態(tài)分布圖。

　　選中正態(tài)分布曲線→右鍵→設(shè)置數(shù)據(jù)列格式→線型→勾選“平滑線”→關(guān)閉。

　　大功告成!!!

　　本例中原始數(shù)據(jù)：

　　51.7,50.6,57.9,56.9,56.7,56.7,55.3,56.1,53.7,54.5,56.9,51.9,52.1,55.1,54.9,54.7,55.3,55.3,54.5,54.9,54.5,55.3,54.9,54.3,53.7,53.5,53.7,53.1,54.5,53.1,53.9,53.5,53.3,53.9,53.5,53.5,52.5,53.3,53.5,53.3,53.7,53.1,54.5,53.9,56.7,54.5,54.3,55.1,54.1,54.5,53.9,53.1,53.3,55.3,55.7,56.1,54.7,53.1,53.3,52.7,53.1,52.9,53.1,54.3,53.1,52.7,53.1,53.3,53.1,53.3,53.1,53.3,55.1,54.7,54.9,54.3,53.9,53.7,53.9,53.5,54.5,54.3,55.5,55.7,55.5,54.9,55.3,55.5,53.7,54.1,53.9,55.7,55.9,53.7,53.5,53.1,52.3,52.7,52.9,53.3,53.9,52.7,53.5,53.1,52.7,51.9,52.5,53.9,54.5,55.7,55.3,54.9,53.1,52.9,54.1,53.3,54.7,53.9,54.3,54.1,53.7,53.3,52.7,52.9,52.5,53.9,53.5,54.1,54.1,54.7,54.9,54.9,54.1,53.3,52.9,53.7,53.9,54.3,54.1,54.5,54.7,54.9,52.1,52.9,53.5,52.7,53.1,53.1,53.5,52.9,52.9,53.1,53.3,52.7,53.5,53.9,54.9,55.1,54.3,55.1,54.3,54.3,53.9,54.5,54.5,54.3,55.3,54.5,54.9,53.5,52.1,55.3,55.7,55.7,55.5,54.5,57.7,54.7,53.7,53.1,53.7,55.9,56.1,53.9,53.7,53.3,53.9,53.9,54.5,54.7,56.1,55.7,53.1,53.7,53.5,53.9,53.9,53.5,53.3,53.1,52.5,55.9,55.7,54.1,54.3,54.1,54.1,54.5,54.5,55.1,53.1,53.3,54.1,54.3,53.9,54.1,54.7,54.7,53.7,53.1,53.3,52.7,53.5,52.9,53.7,56.5,56.1,55.7,55.5,56.9,57.7,56.5,55.7,54.1,54.7,55.7,55.5,53.1,52.7,53.1,53.3,53.5,54.3,54.1,54.5,54.7,55.7,55.5,54.1,54.3,54.7,53.1,53.3,53.1,52.7,53.1,53.7,53.1,54.7,54.5,55.1,54.7,54.5,56.1,55.7,53.3,52.5,53.7,54.1,53.3,52.1,52.3,53.1,53.3,53.5,53.3,53.1,52.7,53.1,55.7,55.1,54.3,53.7,53.1,52.9,53.1,52.7,52.5,53.1,53.5,53.1,53.3,54.1,55.1,54.9,56.1,55.7,56.5,54.7,53.7
