Calabash Brothers Calabash Brothers (Chinese: 葫蘆娃 ) is a Chinese animation TV series produced by Shanghai Animation Film Studio. In the 1980s the series was one of the most popular animations in China.

Zk， k個(gè)獨(dú)立標(biāo)準(zhǔn)正態(tài)變量的平方和被定義為卡方分布（ 2? 分布）的隨機(jī)變量 2? 2? （ k ）＝（ ???1X ）2? （???2X ）2? ? ? （???kX ）2 ＝ ?? ?ki iX122 )(1 ?? ＝ ??ki iZ12 其中 k為卡方分布的自由度， 它表示定義式中獨(dú)立變量的個(gè)數(shù)。 檢驗(yàn)統(tǒng)計(jì)量是關(guān)于樣本的一個(gè)綜合指標(biāo)，但與參數(shù)估計(jì)中討論的統(tǒng)計(jì)量有所不同，它不用作估測，而只用作檢驗(yàn)。 15．眾數(shù) 在一組資料中，出現(xiàn)次數(shù)（或頻數(shù)）呈現(xiàn)“峰”值的那些變量值。 9．樣本和（或）樣本總體 樣本或樣本總體，是通過抽樣得到的用以推斷總體特征的那個(gè)“部分”。因此，一門兼有數(shù)學(xué)和統(tǒng)計(jì)學(xué)雙重意義的學(xué)科被命名為“數(shù)理統(tǒng)計(jì)學(xué)”。 2．國勢學(xué)派 產(chǎn)生于德國，其創(chuàng)始人為康令和阿亨瓦爾。配第。大量觀察法是統(tǒng)計(jì)調(diào)查階段的重要方法 6．大數(shù)規(guī)律 大數(shù)規(guī)律是隨機(jī)現(xiàn)象出現(xiàn)的基本規(guī)律，它的一般意義是：觀察過程中每次取得的結(jié)果可能不同（因?yàn)榫哂信既恍裕罅恐貜?fù)觀察結(jié)果的平均值卻幾乎接近某個(gè)確定的數(shù)值。 12．指標(biāo)體系 指標(biāo)體系就是一系列有內(nèi)在聯(lián)系得統(tǒng)計(jì)指標(biāo)集合體。 18．平均指標(biāo)： 就是表明同質(zhì)總體在一定條件下某一數(shù)量標(biāo)志所達(dá)到的一般水平。若總體單位數(shù)為 N，其中成功類共有 K個(gè)，設(shè)從中抽取n個(gè)為
