用Excel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：4284 | 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(huì)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(jì)算“最大值”、“最小值”、“極差”、“分組數(shù)”、“分組組距”，公式如圖：3. 3分組“分組”就是確定直方圖的橫軸坐標(biāo)

2、起止范圍和每個(gè)小組的起止位置。選一個(gè)比最小值小的一個(gè)恰當(dāng)?shù)闹底鳛榈谝粋€(gè)組的起始坐標(biāo)，然后依次加上“分組組距”，直到最后一個(gè)數(shù)據(jù)值比“最大值”大為止。這時(shí)的實(shí)際分組數(shù)量可能與計(jì)算的“分組數(shù)”有一點(diǎn)正常的差別。類(lèi)似如下圖。4. 4統(tǒng)計(jì)頻率“頻率”就是去統(tǒng)計(jì)每個(gè)分組中所包含的數(shù)據(jù)的個(gè)數(shù)。最簡(jiǎn)單的方法就是直接在所有的數(shù)據(jù)中直接去統(tǒng)計(jì)，但當(dāng)數(shù)據(jù)量很大的時(shí)候，這種方法不但費(fèi)時(shí)，而且容易出錯(cuò)。一般來(lái)說(shuō)有兩種方法來(lái)統(tǒng)計(jì)每個(gè)小組的數(shù)據(jù)個(gè)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)計(jì)的數(shù)據(jù)源，就是

3、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；5. 5生成“FREQUENCY”函數(shù)公式組，步驟如下：1. 先選中將要統(tǒng)計(jì)直方圖每個(gè)子組中數(shù)據(jù)數(shù)量的區(qū)域6. 62. 再按“F2”健，進(jìn)入到“編輯”狀態(tài)7. 73. 再同時(shí)按住“Ctrl”和“Shift”兩個(gè)鍵，再按“回車(chē)Enter”鍵，最后三鍵同時(shí)松開(kāi)，大功告成！8. 8制作直方圖選中統(tǒng)計(jì)好的直方圖每個(gè)小組的分布個(gè)數(shù)的數(shù)據(jù)源（就是“頻率”），用“柱形圖”來(lái)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9. 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(xiàng)

4、，分類(lèi)間距設(shè)置為0%；2、邊框顏色：實(shí)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10. 10直方圖大功造成！END制作正態(tài)分布圖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(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)）2. 向下填充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)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4. 修整圖形1、在圖表區(qū)柱形較

5、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)）。5. 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6. 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7. 2、選中“拆線圖”3、確定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. 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,
