级别: 新手上路
— 本帖被 sunyuting1 从 会员自学日记 移动到本区(2011-02-22) —
下午没课,就把这课的全面注音练了一下,昨天晚上,练的是这一课的简单注音,感觉上是听得还可以,还是手慢,今天下午在20%,30%的速度下进行了全面的注音,
就关于题目 I never thought i'd ask anyone this again 的ask anyone this again的ask anyone的连读 我听了多次才有感觉,后面的this again也是 ,
文中的d,k,p,在词尾的音听得还可以,t在20%听着有 吃 的音,原来也有这样的感觉,不知道是不是这么回事,
to在句中连读是就像 特 的音,
另外那句 we had italian dressing or blue chease dressing 的那个blue总是听不清楚,
with me的连读也是听了几次才听清的,像 don‘t,didn‘t感觉听得也很模糊,fried的f有时听着有b的音,不知道听得对不对,
那句 will you marry me 的will you 的l与you的连读听着像d you。,那句do you have fried chicken的have 的ha听不出来,只听得有do you ve 好像,
那句i want to talk about us 的about us听着有点像 abls,不知道是不是跟talk的l有连读;
老师看看我上面的是不是对什么的
还有一些 东西,来不及写,明天来下午也没课,
正好还可以比较充分的练一下

教训
今天下午考了一下六级,满以为应该是不错的,可是结果感觉特别差劲,听力又是没有听懂什么,阅读题做得很慢,时间很紧张,就有不过脑子的感觉,估计这次又过不了了,有点觉得丢人

由此一看,我根本就没达到深度听清,其实在平时练习中我也有此感觉,听力都是处在一个听清但听不懂的程度,这些天略读的多,精读的少,以致考试时阅读总是不能把心静下来,听写也没有写出来,压码水平还差得远,显然还是压不住,单词量也不够

归根到底,还是我平时练习偷懒,既没有认真的练习方法,也没有协调好与其它课的安排,由此一看,我的英语之路还是任重道远.

Cosmology 宇宙学
Main article: Physical cosmology主要文章: 物理宇宙学

Cosmology (from the Greek κοσμος "world, universe" and λογος "word, study") could be considered the study of the universe as a whole.宇宙学(来自希腊语κοσμος “世界,宇宙”和λογος “字,学习” )可以被认为是宇宙研究的整体。

Observations of the large-scale structure of the universe , a branch known as physical cosmology , have provided a deep understanding of the formation and evolution of the cosmos.意见的大尺度结构的宇宙 ,一个分支称为物理宇宙学 ,提供了一个深入了解的形成与演化的宇宙。 Fundamental to modern cosmology is the well-accepted theory of the big bang , wherein our universe began at a single point in time, and thereafter expanded over the course of 13.7 Gyr to its present condition.现代宇宙学的基本是公认的理论, 宇宙大爆炸 ,其中我们的宇宙开始于一个单一的时间点,并在其后扩大的过程中13.7 Gyr其现状。 The concept of the big bang can be traced back to the discovery of the microwave background radiation in 1965.这一概念的大爆炸,可以追溯到发现微波背景辐射在1965年。

In the course of this expansion, the universe underwent several evolutionary stages.在这次扩张,宇宙的演化经历了几个阶段。 In the very early moments, it is theorized that the universe experienced a very rapid cosmic inflation , which homogenized the starting conditions.在非常早的时刻,这是理论,认为宇宙经历了非常迅速的宇宙通货膨胀 ,这趋同的出发条件。 Thereafter, nucleosynthesis produced the elemental abundance of the early universe.此后, 核合成制作的元素丰度的早期宇宙。 (See also nucleocosmochronology .) (另见nucleocosmochronology 。 )

When the first atoms formed, space became transparent to radiation, releasing the energy viewed today as the microwave background radiation.当第一个原子形成的,以空间变得透明,以辐射,释放的能量看待今天的微波背景辐射。 The expanding universe then underwent a Dark Age due to the lack of stellar energy sources. [ 49 ]不断扩大的宇宙然后经历了黑暗时代,由于缺乏恒星能源。 [ 49 ]

A hierarchical structure of matter began to form from minute variations in the mass density.层次结构的物质开始形成从分钟不同的密度。 Matter accumulated in the densest regions, forming clouds of gas and the earliest stars .问题中积累的最密集的区域,形成的气体云和最早的恒星 。 These massive stars triggered the reionization process and are believed to have created many of the heavy elements in the early universe which tend to decay back to the lighter elements extending the cycle.这些大质量恒星触发了电离过程,被认为是创造了许多的重元素在早期宇宙往往衰变回到轻元素延长周期。

Gravitational aggregations clustered into filaments, leaving voids in the gaps.引力聚集分为长丝,留下空隙中的空白。 Gradually, organizations of gas and dust merged to form the first primitive galaxies.渐渐地,组织的气体和尘埃合并为第一原始星系。 Over time, these pulled in more matter, and were often organized into groups and clusters of galaxies, then into larger-scale superclusters. [ 50 ]随着时间的推移,这些恼人的更多的问题,往往被组织成团体和集群的星系,然后到较大规模的超。 [ 50 ]

Fundamental to the structure of the universe is the existence of dark matter and dark energy .基本的结构是宇宙的存在暗物质和暗能量 。 These are now thought to be the dominant components, forming 96% of the density of the universe.这些都是现在认为是主要的组成部分,形成96 %的密度的宇宙。 For this reason, much effort is expended in trying to understand the physics of these components. [ 51 ]为此,花费了很大的努力是在试图了解物理学这些组件。 [ 51 ]

Interdisciplinary studies  跨学科研究

Astronomy and astrophysics have developed significant interdisciplinary links with other major scientific fields. Archaeoastronomy is the study of ancient or traditional astronomies in their cultural context, utilizing archaeological and anthropological evidence. Astrobiology is the study of the advent and evolution of biological systems in the universe, with particular emphasis on the possibility of non-terrestrial life.天文学和天体物理学发展重大学科与其他主要的科学领域。 Archaeoastronomy是研究古代或传统astronomies在其文化背景,利用考古和人类学的证据。 天体生物学是研究的出现和演变的生物系统在宇宙中,特别强调的可能性,非陆地生活。

The study of chemicals found in space, including their formation, interaction and destruction, is called Astrochemistry .这项研究的化学品中发现的空间,包括它们的形成,互动和破坏,被称为Astrochemistry 。 These substances are usually found in molecular clouds , although they may also appear in low temperature stars, brown dwarfs and planets. Cosmochemistry is the study of the chemicals found within the Solar System , including the origins of the elements and variations in the isotope ratios.这些物质通常是在分子云 ,尽管他们也可能出现在低温星,褐矮星和行星。 宇宙化学是研究发现的化学品的太阳能系统 ,包括起源的要素和不同的同位素比值。 Both of these fields represent an overlap of the disciplines of astronomy and chemistry.这两个领域是一个重叠的各学科的天文学和化学。

Amateur astronomy  业余天文学
Main article: Amateur astronomy主要文章: 业余天文学
Amateur astronomers can build their own equipment, and can hold star parties and gatherings, such as Stellafane .天文爱好者可以建立自己的设备,以及可容纳各方明星和集会,如Stellafane 。

Astronomy is one of the sciences to which amateurs can contribute the most [ 52 ] .天文学是一个科学的业余爱好者能够有助于最[ 52 ] 。

Collectively, amateur astronomers observe a variety of celestial objects and phenomena sometimes with equipment that they build themselves .集体业余天文学家观察各种天体和现象有时设备 , 它们自身建设 。
Common targets of amateur astronomers include the Moon, planets, stars, comets, meteor showers, and a variety of deep-sky objects such as star clusters, galaxies, and nebulae.共同目标的业余天文学家包括月球,行星,恒星,彗星,流星雨,以及各种深空天体 ,如恒星群,星系和星云。 One branch of amateur astronomy, amateur astrophotography , involves the taking of photos of the night sky.一间分行的业余天文学,业余天文摄影 ,涉及到的照片夜空。
Many amateurs like to specialize in the observation of particular objects, types of objects, or types of events which interest them. [ 53 ] [ 54 ]许多业余爱好者想专注于特定的观察对象,类型的对象,或类型的活动,使他们感兴趣的。 [ 53 ] [ 54 ]

Most amateurs work at visible wavelengths, but a small minority experiment with wavelengths outside the visible spectrum.大多数业余工作波长在可见的,但少数人实验波长以外的可见光谱。
This includes the use of infrared filters on conventional telescopes, and also the use of radio telescopes.这包括使用红外线常规望远镜,并使用射电望远镜。 The pioneer of amateur radio astronomy was Karl Jansky who started observing the sky at radio wavelengths in the 1930s.的先驱业余无线电天文学卡尔詹斯基谁观测天空开始在无线电波长在20世纪30年代。 A number of amateur astronomers use either homemade telescopes or use radio telescopes which were originally built for astronomy research but which are now available to amateurs ( eg the One-Mile Telescope ). [ 55 ] [ 56 ]一些业余天文学家使用自制的望远镜或使用射电望远镜原来内置的天文学研究,但目前已提供给业余爱好者( 例如 一英里望远镜 ) 。 [ 55 ] [ 56 ]

Amateur astronomers continue to make scientific contributions to the field of astronomy.业余天文学家继续作出贡献的科学领域的天文学。 Indeed, it is one of the few scientific disciplines where amateurs can still make significant contributions.实际上,它是少数学科在业余爱好者仍然可以作出重要的贡献。 Amateurs can make occultation measurements that are used to refine the orbits of minor planets.业余可以掩星测量,用于完善轨道小行星。 They can also discover comets, and perform regular observations of variable stars.他们还可以发现彗星,并进行定期观测的变星。 Improvements in digital technology have allowed amateurs to make impressive advances in the field of astrophotography. [ 57 ] [ 58 ] [ 59 ]数字化技术的改进,使业余爱好者能够令人印象深刻的进步领域的天文摄影。 [ 57 ] [ 58 ] [ 59 ]

Laozi is traditionally regarded as the author of the Daodejing (Tao Te Ching), though its authorship has been debated throughout history. [ 2 ] [ 3 ] [ 4 ]老子是历来被视为作者的Daodejing (陶特青) ,但其作者已辩论整个历史。 [ 2 ] [ 3 ] [ 4 ]
The earliest reliable reference (circa 100 BC) to Laozi is found in the Records of the Grand Historian ( Shiji ) by Chinese historian Sima Qian (ca. 145–86 BC), which combines three stories.最早的可靠参考(大约100年) ,以老子被发现在该史记 ( 世纪 )的中国史学家司马迁 (约公元前145-86 ) ,它结合了三个故事。
In the first, Laozi was said to be a contemporary of Confucius (551-479 BC).第一,老子被说成是当代的孔子 (公元前551-479 ) 。
His surname was Li ( 李 "plum"), and his personal name was Er ( 耳 "ear") or Dan ( 聃 "long ear").他的姓是李( 李 “梅花” ) ,以及他个人的名字是呃( 耳 “耳朵” )或丹( 聃 “长耳朵” ) 。
He was an official in the imperial archives, and wrote a book in two parts before departing to the West.他是一个正式的帝国档案,并写了一本书分为两部分离开之前向西方。
In the second, Laozi was Lao Laizi ( 老來子 "Old Master"), also a contemporary of Confucius, who wrote a book in 15 parts.第二,老子是老挝Laizi ( 老来子 “老夫子” ) ,也有当代的孔子,谁写了一本书在15个部分。
In the third, Laozi was the Grand Historian and astrologer Lao Dan ( 老聃 "Old Long-ears"), who lived during the reign (384-362 BC) of Duke Xian (獻公) of Qin) . [ 5 ] [ 6 ]第三,老子是史记和占星家老挝丹( 老聃 “老长耳朵” ) ,谁住时期( 384-362年)的杜克大学西安(献公)的秦) 。 [ 5 ] [ 6 ]
Popular legends say that he was conceived (怀孕)when his mother gazed upon a falling star, stayed in the womb for sixty-two years, and was born when his mother leaned against a plum tree.热门传说说,他的构想时,他的母亲凝视一个陨星,停留在腹中的六二年,以及出生时,他的母亲靠在梅树。
He accordingly emerged a grown man with a full grey beard and long earlobes, which are a symbol of wisdom and long life. [ 7 ] [ 8 ] In other versions he was reborn in some thirteen incarnations since the days of Fuxi ; in his last incarnation as Laozi he lived to nine hundred and ninety years, and traveled to India to reveal the Dao. [ 9 ]因此,他出现了增长男子全灰色的胡须和长期耳垂,这是智慧的象征,使用寿命长。 [ 7 ] [ 8 ]在其他版本,他在一些重生的化身,因为13天的伏羲 ;在他的上化身为老子他住到九百九十零年,并前往印度透露道。 [ 9 ]
According to popular traditional biographies, he worked as the Keeper of the Archives for the royal court of Zhou .根据流行的传统的传记,他担任门将档案的皇家法院周 。
This reportedly allowed him broad access to the works of the Yellow Emperor and other classics of the time.据说这使他广泛地获取工作的黄帝和其他经典的时间。
The stories[ assert] that Laozi never opened a formal school, but he nonetheless attracted a large number of students and loyal disciples.故事[说],老子从来没有开设了正规的学校,但他仍然吸引了大批学生和忠实的门徒。
There are numerous variations of a story  depicting Confucius consulting Laozi about rituals. [ 10 ] [ 11 ]有许多变化的一个故事描绘孔子咨询老子约仪式。 [ 10 ] [ 11 ]
According to legends, Laozi leaves China on his water buffalo . [ 12 ]据传说,老子离开中国,他水牛 。 [ 12 ]
Many of the popular accounts say that Laozi married and had a son named Zong, who became a celebrated soldier.许多受欢迎的帐户说,老子结婚并生了一个儿子命名为宗,谁成为庆祝士兵。
A large number of people trace their lineage back to Laozi, as the emperors of the Tang Dynasty did.许多人追查其谱系回到老子,作为皇帝的唐代没有。
According to Simpkins & Simpkins, many (if not all) of the lineages may be inaccurate.据辛普金斯&辛普金斯,许多(如果不是全部的话)的谱系可能不准确。
However, they are a testament to the impact of Laozi on Chinese culture. [ 13 ]然而,他们证明了老子的影响,对中华文化。 [ 13 ]
Traditional accounts state that Laozi grew weary of the moral decay of city life and noted the kingdom's decline.传统的账户状态老子增长厌倦道德败坏城市生活,并指出国的下降。
According to these legends, he ventured west to live as a hermit in the unsettled frontier at the age of 160.根据这些传说,他大胆西作为一个生活在不稳定的隐士前沿的年龄为160 。 At the western gate of the city, or kingdom, he was recognized by a guard.在西区门的城市,或英国,他是公认的一名警卫。 The sentry asked the old master to produce a record of his wisdom.该哨兵问老师傅制作的记录他的智慧。 This is the legendary origin of the Daodejing .这是传奇起源Daodejing 。 In some versions of the tale, the sentry is so touched by the work that he leaves with Laozi to never be seen again.在某些版本的故事,是如此的哨兵所感动,他的工作与老子留下来永远不会再次出现。 Some legends elaborate further that the "Old Master" was the teacher of the Buddha , or the Buddha himself. [ 14 ] [ 15 ]有些传说进一步阐述说, “老夫子”是教师的佛像 ,或佛本人。 [ 14 ] [ 15 ]
By the mid-twentieth century, a consensus had emerged among scholars that the historicity of Laozi was doubtful or unprovable and that the Daodejing was "a compilation of Taoist sayings by many hands originating in the 4th century BC." [ 16 ] Alan Watts (1975) held that this view was part of an academic fashion for skepticism about historical spiritual and religious figures, arguing that not enough would be known for years, or possibly ever, to make a firm judgment. [ 17 ]到二十世纪中叶,已经出现一致意见,学者之间的历史性老子是怀疑或unprovable而且Daodejing是“汇编道教说法,许多双手原产于公元前4世纪。 ” [ 16 ] 阿兰瓦 ( 1975年)认为,这种看法是一个学术时尚的怀疑精神的历史和宗教人士,认为没有足够的将称为多年,或可能以往任何时候都作出坚定的判断。 [ 17 ]

Laozi's magnum opus , the Daodejing , is one of the most significant treatises in Chinese cosmogony .老子的大作品 ,在Daodejing ,是其中一项最重要的论文中宇宙 。
{As with most other ancient Chinese philosophers, Laozi often explains his ideas by way of paradox, analogy, appropriation of ancient sayings, repetition, symmetry, rhyme, and rhythm.与大多数其他古代哲学家老子往往解释他的想法矛盾的方式,类比,拨款古老谚语,重复,对称,押韵,和节奏。}

历史
Main article: History of statistics主要文章: 历史统计

"Five men, Conring , Achenwall , Süssmilch , Graunt and Petty have been honored by different writers as the founder of statistics." claims one source (Willcox, Walter (1938) The Founder of Statistics . Review of the International Statistical Institute 5(4):321-328.) “五男, Conring , Achenwall , Süssmilch , Graunt和佩蒂被评为不同作家的创始人统计。 ”索赔一个来源( Willcox ,瓦尔特( 1938年) 创办的统计 。审查国际统计学会第5 ( 4 ) :321 - 328 。 )

Although it was originally thought that statistics were invented in 1662, new research indicates that statistics were actually discovered 6 years earlier.虽然原先以为的统计数字,在1662年发明,新的研究表明,实际的统计数字,是早期发现的6岁。
By the time he completed the Down Survey in 1656, William Petty had successfully invented statistics for the first time.的时候,他完成了唐氏调查在1656年,威廉配第已经成功地发明了统计首次。 In 1685 it was published as "Hiberniae Delineatio." [ citation needed ]这是在1685年出版的“ Hiberniae Delineatio 。 ” [ 引文需要 ]

Some scholars pinpoint (exactly point)the origin of statistics to 1662, with the publication of " Observations on the Bills of Mortality " by John Graunt .一些学者指出的起源统计数字, 1662年,出版的“ 观察票据的死亡率 ”的约翰Graunt 。
Early applications of statistical thinking revolved around the needs of states to base policy on demographic and economic data, hence its stat- etymology .早期应用统计思想是围绕着国家的需求为基础的政策的人口和经济数据,因此其统计,词源 。 The scope of the discipline of statistics broadened in the early 19th century to include the collection and analysis of data in general.的范围,扩大统计学科在19世纪初,包括数据的收集和分析的一般。 Today, statistics is widely employed in government, business, and the natural and social sciences.今天,统计数据被广泛采用政府,企业,以及自然科学与社会科学。

Because of its [empirical ]roots and its applications, statistics is generally considered not to be a subfield of pure mathematics, but rather a distinct branch of applied mathematics.由于它的经验根及其应用,统计数据通常被认为是不是一个子集的纯数学,而是一个独特的分支应用数学。

Its mathematical foundations were laid in the 17th century with the development of probability theory by Pascal and Fermat .其数学奠定了基础在17世纪的发展, 概率论的帕斯卡和费马 。

Probability theory arose from the study of games(赌博) of chance.概率论的研究是由游戏的机会。 The method of least squares was first described by Carl Friedrich Gauss around 1794.在最小二乘法首次描述卡尔弗里德里希高斯在1794年。
The use of modern computers has expedited large-scale statistical computation, and has also made possible new methods that are impractical to perform manually.利用现代计算机加速了大规模的统计计算,也取得了新的可能方法,是不用实际的手动执行。

概况
    This section may require cleanup to meet Wikipedia's quality standards .本节可能需要清理 ,以满足维基百科的质量标准 。    
In applying statistics to a scientific, industrial, or societal problem, it is necessary to begin with a process or population to be studied.在运用统计数据,以科学,工业,或社会问题,有必要开始一个进程或种群进行研究。
This might be a population of people in a country, of [crystal (水晶)grains(*比喻像谷物)] in a rock, or of goods manufactured by a particular factory during a given period.这可能是一个人口的人在一个国家,在晶粒的岩石,或生产的货物特别是工厂在一定时期内。
It may instead be a process observed at various times; data collected about this kind of "population" constitute what is called a time series .它可能是一个过程而不是在不同的时间观察;数据收集这样的“人口”构成所谓的时间序列 。
For practical reasons, rather than compiling data about an entire population, a chosen subset of the population, called a sample , is studied.
出于实际考虑,而不是数据编制整个人口,一个子集选择的人口,所谓的样品 ,进行了研究。
*population应该指的是全体或整体
Data are collected about the sample in an observational or experimental setting.数据的收集的样本中观测或实验设置。
The data are then subjected to statistical analysis, which serves two related purposes: description and inference.这些数据然后遭受的统计分析,因为这两个相关的目的:描述和推理。
Descriptive statistics can be used to summarize the data, either numerically or graphically, to describe the sample. 描述性统计可以用来总结数据,无论是数字或图形,描述了范例。
Examples of numerical descriptors include the mean and standard deviation for continuous data , such as height, and frequency and percentage for categorical data , such as race.数值描述的例子包括: 平均和标准偏差的连续数据 ,如身高,以及频率和百分比分类数据 ,如种族。
Inferential statistics is used to model patterns in the data,[ accounting for(占)] randomness and drawing inferences about the larger population. 统计推断是用来示范模式的数据,占随机性和借鉴推论有关的人口。
These inferences may take the form of answers to yes/no questions ( hypothesis testing ), estimates of numerical characteristics ( estimation ), descriptions of association ( correlation ), or modeling of relationships ( regression ).这些推论可能采取的形式回答是/否问题( 假设检验 ) ,估计的数值特征( 估计 ) ,说明协会( 相关 ) ,或造型的关系( 回归 ) 。 Other modeling techniques include ANOVA , time series , and data mining .其他建模方法包括方差分析 , 时间序列和数据挖掘 。
“... “ ... it is only the manipulation of uncertainty that interests us.这仅仅是操纵的不确定性,我们的利益。 We are not concerned with the matter that is uncertain.我们不关心的问题是不确定的。 Thus we do not study the mechanism of rain; only whether it will rain.”因此,我们不学习的机制,雨,只有是否会下雨。 “
— Dennis Lindley , "The Philosophy of Statistics", The Statistician (2000). - 丹尼斯林德利 , “统计的哲学” 的统计 ( 2000年) 。    
The concept of correlation is particularly noteworthy.相关的概念,尤其值得注意。
Statistical analysis of a data set may reveal that two variables (that is, two properties of the population under consideration) tend to vary together, as if they are connected.统计分析数据集可能会发现,两个变量(即两个属性的人口正在考虑)往往不同在一起,因为如果它们连接。
For example, a study of annual income and age of death among people might find that poor people tend to have shorter lives than affluent people.例如,一项研究年度的收入和年龄死亡的人可能会发现,穷人往往比富人更短的生命的人。
The two variables are said to be correlated (which is a positive correlation in this case).这两个变量的说是相关性(这是一个积极的相关性在这种情况下) 。
However, one cannot immediately infer the existence of a causal relationship between the two variables(See Correlation does not imply causation .) .然而,一个无法立即推断存在因果关系的两个变量。(见相关性并不意味着因果关系 。 )
The correlated phenomena could be caused by a third, previously unconsidered phenomenon, called a lurking variable or confounding variable . 的相关现象可能造成的三分之一,先前未被考虑的现象,称为潜伏变量或混杂变量 。
If the sample is representative of the population, then inferences and conclusions made from the sample can be extended to the population as a whole.如果样本能够代表的人口,然后推论和结论,从样品可以推广到全体人民。
A major problem lies in determining the extent to which the chosen sample is representative.一个主要问题在于确定在何种程度上选择样本的代表性。
Statistics offers methods to estimate and correct for randomness in the sample and in the data collection procedure, as well as methods for designing robust experiments in the first place.统计资料提供的方法来估计和正确的随机性的抽样和数据收集程序,以及健全的方法,设计实验摆在首位。 (See experimental design .) (见实验设计 。 )
The fundamental mathematical concept employed in understanding such randomness is probability . Mathematical statistics (also called statistical theory ) is the branch of applied mathematics that uses probability theory and analysis to examine the theoretical basis of statistics.基本的数学概念的理解,例如采用随机性的概率 。 数理统计 (也称为统计理论 )是部门的应用数学 ,利用概率论与分析 ,研究的理论基础的统计数据。
The use of any statistical method is valid only when the system or population under consideration satisfies the basic mathematical assumptions of the method. Misuse of statistics can produce subtle but serious errors in description and interpretation — subtle in the sense that even experienced professionals sometimes make such errors, serious in the sense that they may affect, for instance, social policy, medical practice and the reliability of structures such as bridges.使用任何有效的统计方法是仅当系统或人口正在考虑满足基本的数学假设的方法。 滥用统计数字可以产生微妙的,但严重的错误的描述和解释-微妙的意义上,即使有经验的专业人员有时使这种错误,严重的意义上说,可能会影响,例如,社会政策,医疗实践和结构的可靠性,如桥梁。
Even when statistics is correctly applied, the results can be difficult for the non-expert to interpret.即使在统计数据是正确适用,其结果可能是困难的非专家来解释。 For example, the statistical significance of a trend in the data, which measures the extent to which the trend could be caused by random variation in the sample, may not agree with one's intuitive sense of its significance.例如, 统计意义的一种趋势的数据,措施的程度,这种趋势可能是随机变化所造成的样品中,可能不同意一个人的直观意义上的意义。
The set of basic statistical skills (and skepticism) needed by people to deal with information in their everyday lives is referred to as statistical literacy .这套基本统计技巧(和怀疑)所需要的人来处理信息,在日常生活中被称为统计知识 。
Statistical methods  统计方法
Experimental and observational studies  实验和观测研究
A common goal for a statistical research project is to investigate causality , and in particular to draw a conclusion on the effect of changes in the values of predictors or independent variables on dependent variables or response.一个共同的目标的一项统计研究项目是调查的因果关系 ,特别是要得出一个结论:对变化的影响因素的价值观或独立变量对因变量或响应。
There are two major types of causal statistical studies: experimental studies and observational studies.主要有两种类型的因果关系的统计研究:实验研究和观察研究。 In both types of studies, the effect of differences of an independent variable (or variables) on the behavior of the dependent variable are observed.在两种类型的研究,对不同的一个独立的变量(或变量)的行为的变量得到遵守。 The difference between the two types lies in how the study is actually conducted.两者之间的差额类型在于如何进行实际研究。 Each can be very effective.每个国家都非常有效。
An experimental study involves taking measurements of the system under study, manipulating the system, and then taking additional measurements using the same procedure to determine if the manipulation has modified the values of the measurements.涉及的实验研究的测量系统的研究,操纵系统,然后采取进一步的测量使用相同的程序,以确定是否操纵改变了价值观的测量。
In contrast, an observational study does not involve experimental manipulation.与此相反,一个观测研究不涉及实验操作。 Instead, data are gathered and correlations between predictors and response are investigated.相反,数据收集和相关性的预测和反应的影响。
An example of an experimental study is the famous Hawthorne studies , which attempted to test the changes to the working environment at the Hawthorne plant of the Western Electric Company.一个实例的实验研究是著名的霍桑研究 ,试图测试改变工作环境,在霍桑工厂的西方电气公司。 The researchers were interested in determining whether increased illumination would increase the productivity of the assembly line workers.研究人员有兴趣在确定是否将增加照明增加生产力的装配线工人。
The researchers first measured the productivity in the plant, then modified the illumination in an area of the plant and checked if the changes in illumination affected the productivity.研究人员首先测量了生产力的工厂,然后修改了照明领域中的植物和检查,如果光照变化影响生产力。
It turned out that the productivity indeed improved (under the experimental conditions).事实证明,生产率确实提高(在实验条件下) 。 However, the study is heavily criticized today for errors in experimental procedures, specifically for the lack of a control group and blindness .然而,这项研究是严厉批评错误,今天的实验程序,特别是缺乏一个对照组和失明 。
The Hawthorne effect refers to finding that an outcome (in this case worker productivity) change due to observation itself.在霍桑效应是指发现的结果(在这种情况下,工人的生产力)的变化,由于观测本身。 Those in the Hawthorn studies became more productive not because the lighting was changed but because they were being observed.那些在山楂研究变得更加富有成效,这倒不是因为照明改变,而是因为他们被发现。
An example of an observational study is a study which explores the correlation between smoking and lung cancer.一个例子,一个观测研究是研究,探讨了相关吸烟与肺癌之间。 This type of study typically uses a survey to collect observations about the area of interest and then performs statistical analysis.这种类型的研究通常使用的调查,收集意见,对感兴趣的领域,然后进行统计分析。
In this case, the researchers would collect observations of both smokers and non-smokers, perhaps through a case-control study , and then look for the number of cases of lung cancer in each group.在这种情况下,研究人员将收集的意见都吸烟者和非吸烟者,也许通过病例对照研究 ,然后查找案件的数目肺癌各组。
The basic steps of an experiment are;的基本步骤进行实验的;
Planning the research, including determining information sources, research subject selection, and ethical considerations for the proposed research and method.规划的研究,包括确定信息来源,研究课题的选择,和道德的考虑拟议的研究和方法。
Design of experiments , concentrating on the system model and the interaction of independent and dependent variables. 实验设计 ,集中于系统模型和互动的独立和依赖的变数。

[ edit ] Levels of measurement [ 编辑 ] 水平的测量
Main article: levels of measurement主要文章: 水平的测量
There are four types of measurements or levels of measurement or measurement scales used in statistics: nominal, ordinal, interval, and ratio.有四种类型的测量或水平的测量或测量表用于统计:名义,有序,间隔和比率。
They have different degrees of usefulness in statistical research .他们有不同程度的有用的统计研究 。
Ratio measurements have both a zero value defined and the distances between different measurements defined; they provide the greatest flexibility in statistical methods that can be used for analyzing the data.比测量都为零界定和价值之间的距离不同的测量定义;他们提供了最大的灵活性,统计方法,可用于分析的数据。
Interval measurements have meaningful distances between measurements defined, but have no meaningful zero value defined (as in the case with IQ measurements or with temperature measurements in Fahrenheit ).间隔测量有意义之间的距离测量界定,但没有取得有意义的零值定义(如与智商测量或温度测量华氏 ) 。
Ordinal measurements have imprecise differences between consecutive(continuous) values, but have a meaningful order to those values.序测量不精确连续值之间的差异,但有一个有意义的,以这些价值观。
Nominal measurements have no meaningful [rank order ]among values.标称测量没有任何有意义的[排序]中的价值。
Since variables [conforming ]only to nominal or ordinal measurements cannot be reasonably measured numerically, sometimes they are called together as categorical variables, whereas ratio and interval measurements are grouped together as quantitative or continuous variables due to their numerical nature.自变量只是名义上[符合]或序测量不能合理测量数值,有时他们被称为作为绝对变量,而比率和间隔测量组合数量或连续变量的数值,由于其性质。

If various studies appear to contradict one another, then the public may come to distrust such studies. 如果各项研究似乎相互矛盾,那么,公众可能会不信任这样的研究。
For example, one study may suggest that a given diet or activity raises blood pressure , while another may suggest that it lowers blood pressure.例如,一项研究表明,特定的饮食或活动引起的血压 ,而另一个可能表明,降低血压。
The discrepancy can arise from subtle (不明显)variations in experimental design, such as differences in the patient groups or research protocols, that are not easily understood by the non-expert.这种差异可能会出现微妙的变化,从实验设计,如不同的患者群体或研究协议,这是不容易理解的非专家。
(Media reports usually omit this vital contextual information entirely, because of its complexity.) (媒体报道通常省略这一重要背景资料完全,因为它的复杂性。 )
By choosing (or rejecting, or modifying) a certain sample, results can be manipulated.选择(或拒绝,或修改)某些样品,结果被操纵。
Such manipulations need not be [malicious] or [devious]; they can arise from unintentional biases (prejudice)of the researcher.这种操纵不必恶意或不正当的;他们能够产生无意偏见的研究员。
The graphs used to summarize data can also be misleading.图表用来总结数据也可以使人产生误解。
Deeper criticisms come from the fact that the hypothesis testing approach, widely used and in many cases required by law or regulation, forces one hypothesis (the null hypothesis ) to be "favored", and can also seem to exaggerate the importance of minor (次要)differences in large studies.
更深的批评来自于这样一个事实,即假设检验的方法,广泛使用,在许多情况下,所需要的法律或法规,部队一个假设(的零假设 )的“青睐” ,也似乎夸大的重要性,稍有差别,大量的研究。
A difference that is highly statistically significant can still be of no practical significance.阿差异具有高度统计学意义仍然可以没有任何实际意义。 (See criticism of hypothesis testing and controversy over the null hypothesis .) (见批评假设检验和争议的零假设 。 )
One response is by giving a greater emphasis on the p -value than simply reporting whether a hypothesis is rejected at the given level of significance.一个反应是通过给予更大的重视p值不仅仅是报告是否假说被拒绝在一定水平的意义。 The p -value, however, does not indicate the size of the effect. 的 P -值,但并不表明的规模效应。
Another increasingly common approach is to report confidence intervals .另一种越来越常见的方法是,报告置信区间 。 Although these are produced from the same calculations as those of hypothesis tests or p -values, they describe both the size of the effect and the uncertainty surrounding it.虽然这些是由相同的计算的那些假设检验或 P -价值观,他们所描述的规模效应和它的不确定性。
Statistics applied to mathematics or the arts 统计应用数学或艺术
Traditionally, Statistics was concerned with [drawing inferences] using a [semi standardized methodology] that was required learning in most sciences.传统上,统计涉及绘画推论半标准化的使用方法,需要学习的最科学。
This has changed with use of Statistics in non-inferential contexts.这种情况已经改变了使用统计数字的非推理背景。 What was considered to be a [dry subject], taken only as a requirement for degrees in many fields, is now viewed enthusiastically.什么被认为是缺水问题,只能作为一个要求度在许多领域,现在是看热情。 What was derided by some mathematical purists is now considered essential methodology in some areas.什么是嘲笑一些数学纯化现在认为是至关重要的方法在某些领域。
Scatter plots of data generated by a [distribution function ] may be transformed with familiar tools used in Statistics to reveal [underlying patterns], which may lead to hypotheses in n[umber theory] .散点图产生的数据的分布函数可转化熟悉的工具来使用的统计显示基本形态,从而可能导致假设数论 。
Methods of Statistics including predictive methods in forecasting , are combined with chaos theory and fractal geometry to create video works considered to be of beauty.方法统计方法,包括预测预报 ,是结合混沌理论和分形几何创建的视频作品被认为是美丽。 The process art of Jackson Pollock relied on artistic experiments  whereby underlying distributions in nature were artistically revealed.该进程艺术的杰克逊波洛克依赖于艺术的实验,使潜在的分布性质的艺术发现。 With the advent of computers, methods of Statistics were applied to formalize such distribution driven natural processes, in order to make and analyze moving video art.随着计算机,统计方法适用于正式分配驱动等自然过程,以便使和分析移动视频艺术。
Methods of Statistics may be used predicatively, not inferentially in performance art , as in a card trick based on a [markov process] that only works some of the time, predicted using statistical methodology.
统计方法可用于predicatively ,而不是inferentially在表演艺术 ,如信用卡欺骗基于马尔可夫过程 ,只有一些作品的时间,预计使用的统计方法。
Statistics is used to predicatively create art, for example in applications of Statistical mechanics with the Statistical or Stochastic music invented by Iannis Xenakis , where the music is performance specific, and does not always come out as expected, but does within a range predicted using Statistics.
统计是用来predicatively创造的艺术,例如在应用统计力学与统计或随机音乐发明Iannis Xenakis ,那里的音乐表现具体,并不总是出来如预期,但预测的范围内使用统计。
