excel2007生成正態(tài)分布曲線圖的方法
excel2007生成正態(tài)分布曲線圖的方法
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，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)分布曲線圖的步驟如下：
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：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)：
