用Excel2007制作直方圖和正態(tài)分布曲線圖

1、用Excel2007制作直方圖和正態(tài)分布曲線圖 | 瀏覽：3677 | 更新：2014-04-15 02:39 | 標(biāo)簽： excel2007 1 2 3 4 5 6 7 分步閱讀 在學(xué)習(xí)工作中總會有一些用到直方圖、正態(tài)分布曲線圖的地方，下面手把手教大家在Excel2007中制作直方圖和正態(tài)分布曲線圖步驟閱讀 工具/原料 Excel(2007)方法/步驟 1. 1數(shù)據(jù)錄入新建Excel文檔，錄入待分析數(shù)據(jù)（本例中將數(shù)據(jù)錄入A列，則在后面引用中所有的數(shù)據(jù)記為A:A）；2. 2計算“最大值”、“最小值”、“極差”、“分組數(shù)”、“分組組距”，公式如圖：步驟閱讀 3. 3分組“分組”就是確定直方圖的橫

2、軸坐標(biāo)起止范圍和每個小組的起止位置。選一個比最小值小的一個恰當(dāng)?shù)闹底鳛榈谝粋€組的起始坐標(biāo)，然后依次加上“分組組距”，直到最后一個數(shù)據(jù)值比“最大值”大為止。這時的實際分組數(shù)量可能與計算的“分組數(shù)”有一點正常的差別。類似如下圖。步驟閱讀 4. 4統(tǒng)計頻率“頻率”就是去統(tǒng)計每個分組中所包含的數(shù)據(jù)的個數(shù)。最簡單的方法就是直接在所有的數(shù)據(jù)中直接去統(tǒng)計，但當(dāng)數(shù)據(jù)量很大的時候，這種方法不但費時，而且容易出錯。一般來說有兩種方法來統(tǒng)計每個小組的數(shù)據(jù)個數(shù)：1.采用“FREQUENCY”函數(shù)；2.采用“COUNT IF”讓后再去相減。這里介紹的是“FREQUENCY”函數(shù)方法：“Date_array”：是選取要統(tǒng)

3、計的數(shù)據(jù)源，就是選擇原始數(shù)據(jù)的范圍；“Bins_array”：是選取直方圖分組的數(shù)據(jù)源，就是選擇分組數(shù)據(jù)的范圍；步驟閱讀 5. 5生成“FREQUENCY”函數(shù)公式組，步驟如下：1. 先選中將要統(tǒng)計直方圖每個子組中數(shù)據(jù)數(shù)量的區(qū)域步驟閱讀 6. 62. 再按“F2”健，進入到“編輯”狀態(tài)步驟閱讀 7. 73. 再同時按住“Ctrl”和“Shift”兩個鍵，再按“回車Enter”鍵，最后三鍵同時松開，大功告成！步驟閱讀 8. 8制作直方圖選中統(tǒng)計好的直方圖每個小組的分布個數(shù)的數(shù)據(jù)源（就是“頻率”），用“柱形圖”來完成直方圖：選中頻率列下所有數(shù)據(jù)（G1:G21),插入柱形圖二維柱形圖步驟閱讀 9.

4、9修整柱形圖選中柱形圖中的“柱子”右鍵設(shè)置數(shù)據(jù)系列格式：1、系列選項，分類間距設(shè)置為0%；2、邊框顏色：實線，白色（你喜歡的就好）3、關(guān)閉“設(shè)置數(shù)據(jù)系列格式”窗口步驟閱讀 10. 10直方圖大功造成！步驟閱讀 END制作正態(tài)分布圖 1. 1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”來計算：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)）步驟閱讀 2. 2向下填充步驟閱讀 3. 3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)

5、據(jù)添加2、系列名稱：選中H1單元格3、系列值：選中H2:H214、確定、確定步驟閱讀 4. 4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，實在看不清，多試幾次，選中后如圖，同時正態(tài)分布曲線那數(shù)數(shù)據(jù)處于選中狀態(tài)）。步驟閱讀 5. 52、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，如圖步驟閱讀 6. 6更改系列圖表類型1、選中正態(tài)分布柱形圖右鍵更改系列圖表類型步驟閱讀 7. 72、選中“拆線圖”3、確定步驟閱讀 8. 8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！9. 9本例中原始數(shù)據(jù)：51.7,50.6,57.9,
