-- :3:19 来源:kekenet阅读模拟题(三) -01- :57:59 来源: Question 1-30  There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental s (state and statistics come from the same Latin root, status) and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering. and the taking of censuses —— all of which led to modern descriptive statistics. From the influence of the father came modern inferential statistics, which is based squarely on theories of probability.  Descriptive statistics involves tabulating, depicting, and describing collections of data. These data may be quantitative, such as measures of height, intelligence, or grade level - variables that are characterized by an underlying continuum - orthe data may represent qualitative variables, such as sex, college major, or personality type. Large masses of data must generally undergo a process of summarization or reduction bee they are comprehensible. Descriptive statistics is a tool describing or summarizing or reducing to comprehensible m the properties of an otherwise unwieldy mass or data. Inferential statistics is a malized body of methods solving another class of?problems that present great difficulties the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child; the proportion the entire district could be estimated fairly accurately from a sample of as few as l00 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from a knowledge of the characteristics of only a sample of the population.  1.

  作文:机器人(文都教育版) --1 :9:9 来源: 年6月18日全国大学英语六级考试已结束,本次考试采取“多题多卷”模式,考后文都教育及时收集整理不同版本试题,供考生参考,以下是年6月六级考试写作及参考范文:论机器人的使用,赶紧看看吧With the development of technology, robots play an increasingly important role in industry and daily lives. People d that robots will take the place of human beings one day both in industry and people’s daily lives completely.In my view, robots will not take the place of human beings totally, though there will be more and more robots. My reasons are as follows. On one hand, robots work by programs and when they encounter difficult issues that are not included in the programs, they cannot solve them. But people can solve difficult problems even they never met them, as we people can accumulate different people’s wits and think out solutions. On the other, robots do not have feelings which are of great importance both to jobs and daily lives. But we people have such feelings. Theree, robots cannot do well in many fields that are involved more with human feelings than technologies.In short, robots will aid people both in industry and people’s daily lives, but they cannot replace the role of human beings.
