專業好文檔經濟師考試中級經濟基礎科目考前復習指導：統計指數篇重點、難點講解及典型例題考點一指數的概念和分類狹義地講，指數是用于測定多個項目在不同場合下綜合變動的一種特殊相對數。目前普遍應用的是加權指數。【例1多選題】按照計入指數的項目多少不同，指數分為()。a.加權指數b.簡單指數c.個體指數d.質量指數e.綜合指數【答案】ce【解析】本題考查指數的分類。按照計入指數的項目多少不同，指數分為個體指數和綜合指數。【例2單選題】下列指數中屬于質量指數的是()。培訓搜px.wangxiao.so培訓網提示您a.商品銷售額指數b.股票價格指數c.商品銷售量指數d.產品產量指數【答案】b【解析】本題考查指數的分類。質量指數反映事物質量的變動水平，如價格指數、產品成本指數等。所以選項b屬于質量指數。考點二加權綜合指數加權綜合指數是通過加權來測定一組項目的綜合變動情況。【例3單選題】下列各項中，屬于帕氏數量指數的是()。【答案】c【解析】本題考查帕氏質量指數和數量指數的一般計算公式。分別是：【例4.單選題】下列各項中，屬于拉氏物價指數的是()。【答案】b【解析】本題考查拉氏質量指數和數量指數的一般計算公式。分別是：考點三指數體系【例5單選題】某企業2009年的工資總額比2008年上升了20%，職工平均人數比2008年下降了10%，則2009年的職工平均工資比2008年()。a.上升30%b.上升33.3%c.上升40%d.下降30%【答案】b【解析】本題考查指數體系的分析與應用。【例6單選題】某企業總生產費用今年比去年上升50%，產量增加25%，則單位成本提高了()。a.25%b.20%c.2%d.87.5%【答案】b【例7多選題】某商場2008年的總銷售額為86000元，2009年為90000元，商品價格上漲10%，與2008年相比，則()。a.商品銷售量指數為95.14%b.總銷售額指數為104.65%c由于價格上漲使總銷售額增加了8182元d.由于商品銷售量下降使總銷售額減少了8182元e.總銷售額增加4000元【答案】abce【解析】本題考查指數體系的分析與應用。考點四幾種常用的價格指數(一)零售價格指數我國編制的價格指數中，與人民生活關系最為密切的是商品零售價格指數和居民消費價格指數。我國零售商品價格指數編制中的主要問題包括：(1)代表規格品的選擇。在編制價格指數時，只能選擇部分具有代表性的商品。(2)典型地隧的選擇。典型地區的選擇既要考慮代表性，也要注意類型上的多樣性以及地區分布上的合理性和穩定性。(3)商品價格的確定。對所選代表性商品使用的足全社會綜合平均價。(4)權數的確定。我國目前的零售價格總指數足采用加權算術平均形式計算的，其權數是根據上年商品零售額資料，并根據當年住戶調查資料予以調整后確定的。(5)指數的汁算。從1985年1月起，我國開始采用部分商品平均價格法計算全社會商品零售價格總指數。其計算公式為：式中，k為個體指數或各層的類指數，w為各層零售額比重權數。【例8多選題】我國目前編制的價格指數中，與人民生活關系最為密切的是()。a.農業生產資料價格指數b.商品零售價格指數c.固定資產投資價格指數d.居民消費價格指數e.農產品收購價格指數【答案】bd【解析】本題考查價格指數。與人民生活關系最為密切的是商品零售價格指數和居民消費價格指數。(二)消費價格指數我國稱為居民消費價格指數1.概念居民消費價格指數是反映一定時期內城鄉居民所購買的生活消費品價格和服務項目價格的變動趨勢和程度的一種相對數。居民消費價格指數可就城鄉分別編制城市居民消費價格指數和農村居民消費價格指數，也可就全社會編制全國居民消費價格總指數。2.作用(1)能夠反映城鄉居民所購買的生活消費品價格和服務項目價格的變動趨勢和程度。(2)能夠反映通貨膨脹的狀況。通貨膨脹的嚴重程度一般用通貨膨脹率來反映，通貨膨脹率一般以居民消費價格指數來表示。其計算公式為：(3)反映貨幣購買力變動。貨幣購買力是指單位貨幣能夠購買到的消費品和服務的數量。居民消費價格指數的倒數就是貨幣購買力指數，其計算公式為：(4)反映對職工實際工資的影響。利用消費價格指數可以將名義工資轉化為實際工資，其計算公式為：【例9單選題】某地居民的消費價格指數為105%，則當地的貨幣購買力指數為()。a.5%b.20%c.95.2%d.102%【答案】c【解析】本題考查貨幣購買力指數的計算。貨幣購買力指數=1/居民消費價格指數=1/105%=95.2%。(三)股票價格指數1.股票價格的影響因素及公式正常情況下，股票價格通常與兩個直接因素相關：預期股息和銀行存款利息率。2.股價平均數股價平均數是股票市場上多種股票在某一時點上的算術平均值，一般以收盤價來計算。其計算公式為：式中，pi為第i種股票的收盤價，n為樣本股票數。因股票市場上股票交易品種繁多，股價平均數(股票價格指數也一樣)只能就樣本股票來計算。但所選擇的樣本股票必須具有代表性和敏感性。3.股票價格指數股票價格指數是反映某一股祭市場上多種股票價格變動趨勢的一種相對數，簡稱股價指數，其單位一般以“點”表忝.即將基期指數作為100，每上升或下降一個單位稱為“1點”。股票價格指數的計算一般以發行量為權數進行加權。【例10單選題】某人購買了上市公司股票1000股，每股票面金額10元，預期每年可以獲6%的股息，而當時銀行存款的年利率為5%，貸款利率為6%，如果沒有其他因素影響，一年后此人購買的每股股票價格是()元。a.5b.8c.10d.12【答案】d【解析】本題考查股票價格的計算。每股股票價格=106%/5%=12(元)。winger tuivasa-sheck, who scored two tries in the kiwis 20-18 semi-final win over england, has been passed fit after a lower-leg injury, while slater has been named at full-back but is still recovering from a knee injury aggravated against usa.both sides boast 100% records heading into the encounter but australia have not conceded a try since josh charnleys effort in their first pool match against england on the opening day.aussie winger jarryd hayne is the competitions top try scorer with nine, closely followed by tuivasa-sheck with eight.but it is recently named rugby league international federation player of the year sonny bill williams who has attracted the most interest in the tournament so far.the kiwi -

winds less than 2 mph, with no precipitation or humidity and limited cloud cover. the balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our day-to-day weather lives. it will climb higher than the tip of mount everest (5.5 miles/8.85 kilometers), drifting even higher than the cruising altitude of commercial airliners (5.6 miles/9.17 kilometers) and into the stratosphere. as he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence.the balloon will slowly drift to the edge of space at 120,000 feet ( then, i would assume, he will slowly step out onto something resembling an olympic diving platform.they blew it in 2008 when they got caught cold in the final and they will not make the same mistake against the kiwis in manchester.five years ago they cruised through to the final and so far history has repeated itself here - the last try they conceded was scored by englands josh charnley in the opening game of the tournament.that could be classed as a weakness, a team under-cooked - but i have been impressed by the kangaroos focus in their games since then.they have been concentrating on the sort of stuff that wins you tough, even contests - strong defence, especially on their own goal-line, completing sets and a good kick-chase. theyve been great at all the unglamorous stuff that often
