統(tǒng)計學的重要性

1、統(tǒng)計學介紹統(tǒng)計學以概率論為基礎的方法論學科，它在幾乎所有的領域里面都具 有重要的應用，統(tǒng)計學知識理論就像我們?nèi)粘Ｊ褂玫碾娔X一樣必不可 少，是現(xiàn)代高級人才必備一種素質，在現(xiàn)代社會中沒有統(tǒng)計學知識的 人就如同一“文盲”.統(tǒng)計學在人類活動當中舉足輕重.統(tǒng)計學在工業(yè)、商業(yè)、貿(mào)易、物理 學、化學、經(jīng)濟學、數(shù)學、生物學、植物學、心理學、天文學等等方 面都扮演重要的角色，因此統(tǒng)計學的應用非常廣泛，幾乎涵蓋每一個 領域，下面我們來具體看一下它能運用在哪些方面 .1.統(tǒng)計學將幫助您成為一位成功的商人.成功的商人必須能夠快速 準確做出決策.如果你知道客戶需要什么，那么你就知道該生產(chǎn)什 么，生產(chǎn)多少.統(tǒng)計學將能幫助

2、你制定生產(chǎn)計劃，同時也能幫助你 有效地檢驗產(chǎn)品質量，它能讓你在關于企業(yè)地理位置、產(chǎn)品營銷、 金融資源等問題上做出正確的決定.1) Business:Statistics play an importa nt role in bus in ess. A successful bus in essma n must be very quick and accurate in decision making. He knows that what his customers wan ts, he should therefore, know what to produceand sell and i

3、n what qua ntities. Statistics helps bus in essma n to pla n product on accord ing to the taste of the costumers, the quality of the products can also be checked more efficiently by using statistical methods. So all the activities of the bus in essma nbased on statistical information. He can make co

4、rrect decision about the location of bus in ess, marketi ng of the products, finan cial resources etc2.如果你想在經(jīng)濟學方面有所發(fā)展，那萬萬是離不開統(tǒng)計學的.經(jīng)濟學在很大程度上依賴于統(tǒng)計學，國民收入帳戶對于經(jīng)濟學家和管 理者來說是具有多重目的性的指標，統(tǒng)計學是建立這些帳戶的基礎.在經(jīng)濟學的研究中統(tǒng)計學方法被用來收集、分析數(shù)據(jù)，并作出檢驗 假設.統(tǒng)計學的方法可以用來研究供求關系，進出口，通貨膨脹， 人均收入等等問題的研究都離不開統(tǒng)計學.(2) In Economics:Statistics pl

5、ay an important role in economics. Economics largely depe nds upon statistics. Nati onal in come acco unts are multipurpose in dicators for the econo mists and admi nistrators. Statistical methods are used for preparati on of these acco un ts. In econo mics research statistical methods are used for

6、collecting and analysis the data and testing hypothesis. The relati on ship betwee n supply and dema nds is studies by statistical methods, the imports and exports, the inflation rate, the per capita in come are the problems which require good kno wledge of statistics.3如果您想在數(shù)學領域有所發(fā)展，請務必學好統(tǒng)計學.統(tǒng)計學與數(shù)學

7、密不可分，他們的很多東西都是互通的.所以想要學好數(shù)學也得要 學好統(tǒng)計學.(3) In Mathematics:Statistical plays a central role in almost all natural and social sciences.The methods of n atural scie nces are most reliable but con clusi ons draw from them are only probable, becausethey are based on in complete evidenee. Statistical helps i

8、n describing these measurements more precisely. Statistics is branch of applied mathematics. The large nu mber of statistical methods like probability averages,dispersions, estimation etc is used in mathematics and different techniques of pure mathematics like integration, differentiation and algebr

9、a are used in statistics.4. 如果您將來想入銀行業(yè)，那么你就離不開統(tǒng)計學.因為銀行在很多的方面必須要用到統(tǒng)計學的方法.(4) In Banking:Statistics play an important role in banking. The banks make use of statistics for a number of purposes. The banks work on the principle that all the people who deposit their money with the banks do not withdraw i

10、t at the same time. The bank earns profits out of these deposits by lending to others on in terest. The ban kers use statistical approaches based on probability to estimate the numbers of depositors and their claims for a certa in day.5. 如果您將來想成為一名管理人才，那么缺乏統(tǒng)計學知識是簡直是 不可想象的事情.許多的國家政策的制定都基于統(tǒng)計數(shù)據(jù)，統(tǒng)計數(shù) 據(jù)是被

11、廣泛用于管理決策.(5) In State Management (Administration):Statistics is essential for a country. Different policies of the government are based on statistics. Statistical data are now widely used in taking all admi nistrative decisi ons. Suppose if the gover nment wants to revise the pay scales of employees

12、 in view of an in crease in the livi ng cost, statistical methods will be used to determ ine the rise in the cost of livi ng. Preparation of federal and provincial government budgets mainly depends upon statistics because it helps in estimating the expected expenditures and revenue from different so

13、urces. So statistics are the eyes of administration of the state.6. 統(tǒng)計學在會計和審計中運用相當廣泛.想學會計與審計的同學統(tǒng) 計學知識是必不可少的.(6) In Accounting and Auditing:Accounting is impossible without exactness.But for decision making purpose, so much precisi on is not esse ntial the decisi on may be take n on the basis of appr

14、oximation, know as statistics. The correction of the values of current asserts is made on the basis of the purchasing power of money or the curre nt value of it.In auditing sampling techniques are commonly used. An auditor determ ines the sample size of the book to be audited on the basis of error.7

15、. 統(tǒng)計學在幾乎所有的自然科學和社會科學中都不可或缺.統(tǒng)計方法被廣泛用來分析實驗結果，檢驗顯著性，比如生物、物理、化學(7) In Natural and Social Sciences:Statistics plays a vital role in almost all the natural and social sciences. Statistical methods are commonly used for analyzing the experiments results, testing their significanee in Biology, Physics, Chem

16、istry,Mathematics, Meteorology, Research chambers of commerce,Sociology, Busin ess, Public Admi nistratio n,Communi cati on andIn formati on Tech no logy etc 8. 如果您有志成為天文學方面的人才，你得學好統(tǒng)計學才行.（8）In Astronomy:Astr onomy is one of the oldest branch of statistical study, it deals withthe measurementof dista

17、nee, sizes, massesand densities of heavenly bodies by means of observati ons. Duri ng these measureme nts errors are unavoidable so most probable measurements are founded by using statistical methods.Example: This distance of moon from the earth is measured. Since old days the astronomers have been

18、statistical methods like method of least squares for finding the moveme nts of stars.大學大多數(shù)學科將會涉及統(tǒng)計學（下面只是其中一些直接以統(tǒng)計為基礎的學科，還有很多專業(yè)或學科也是跟統(tǒng)計學相關的）：Statistics is the mathematical science involving the collection, analysis and interpretation of data.
