Everyone may encounter a scene when he or she wonders what the meaning and purpose of life is. Answers to this question vary from person to person. As for me, I agree with the view that the meaning of life is to discover your gift and the purpose of life is to make the best of it.

On one hand, one's gift could be the source of his inner happiness, providing spiritual impetus and correct orientation. Take the world-renowned Chinese pianist Lang Lang as an example. His gift was noticed before he was 3 years old, which laid the foundation of his glorious life. On the other hand, proper use of talent helps people to realize their value in a positive way, thus making contribution to the society as a whole. For instance, Isaac Newton made a universally amazing discovery by digging into his gift and finding the Newton's law of gravitation.

In conclusion, let's search for our true gift and utilize it to the fullest to achieve a happy and valuable life.

本学期专业开设了统计学课程,通过一学期的学习我们对统计学应用领域及其类型基本概念有了基本了解,掌握了数据的收集、展示、分析的技术。但这都是些书本上的理论知识,是纸上谈兵。然而通过一学期统计学的'学习,由最初对统计学的枯燥乏味的认识,逐渐得到转变,平时学习中的积累,在此次实习中得到了实际应用。

统计学作为应用数学的一个分支,主要通过利用概率论建立数学模型,收集所观察系统的数据,进行量化的分析、总结,并进而进行推断和预测,为相关决策提供依据和参考。统计方法适用于所有学科领域的通用数据分析方法,只要有数据的地方就会用到统计方法。

此次实习我们根据消费者对食品安全的了解情况做了问卷式调查。如果是以我们以前的知识和技术水平,仅会用Excel表格对数据做粗略的统计,多份问卷的数据统计工作需要大量的时间,大量的人力,还有可能出现误差,导致统计结果极不准确,又不能直观反应问卷信息,然而学习了统计学数据分析之后,通过SPSS软件就可以很容易的对事先录入的数据进行分析统计,不但操作简单易学,而且我们可以对数据中无效数据进行排除,对数据结果的个数及比例等进行直观的比较。我们既在实践中提高了动手操作的能力和把理论应用到实践中去的思想,又通过试验加深了我们对课本上理论的认识和掌握。

对于此次的统计学实习,自我感觉还是有很多收获的。首先,我们选择了不同地区、不同年龄、不同职业的群体做了广泛的调查,真正到人群中调查,对食品安全等情况有了更深刻的认识,更真实的反应。其次,从获得的调查问卷数据统计中,也让我认识到了目前食品安全问题依旧严峻,值得大家关注。第三,更重要的是,我们学会用统计学知识整理分析数据,使得理论知识在实际工作中得到应用,理论与实际相结合,是我们学习的重中之重。

此次实习中也有很多的问题,需要在以后的实习中多加注意。例如,调查问卷的设计并不完善,要求不明确,问题的针对性,相关性有待提高。从班级汇总的数据来看,调查人群的年龄较集中,下次应注意选择代表性的人群,平均分配每类人群的调查数。还有就是对于数据的后期分析较浅显,可以增加集体分析讨

论的环节,对各种结果的原因作分析,寻找一些解决方案等,这样可以增强调查的目的性。

通过实习不仅复习了课本知识,通过与实践相结合,对理论知识也有了更深入的了解,学会了对理论的实践应用,增强了我的动手操作的能力和理论与实践相结合的思想。在与小组成员的合作中我学会了以与队友合作的技能、处理和队友之间因工作产生的意见不合的能力。而这些都是在学习理论知识中学不到的,这将对个人以后走上工作岗位都是很有用的技能,这些技能会终身受用。

The Role of Mobile Phone in People's Communication

The popularity of smartphones has exerted great influence on the way people communicate, so much so that an increasing number of individuals contend that face-to-face communication is being replaced by texts and images on the mobile phone.

There are more than one angle to consider this phenomenon. On one hand, it is pleasantly acknowledged that smartphones shorten the distance between families and friends. Even people from different sides of the globe can share pictures, feelings and thoughts through various types of apps on the phone, thus building a long-distance connection. On the other hand, as the picture warns us, too much smartphone addiction interferes with people's real-life communication. Statistics show that over 70 percent of face-to-face communication consists of facial expressions and body language, which is why people should stay away from mobile phones when they have the chance to actually talk and communicate with others.

In a word, mobile phones act as an appropriate platform where people can always stay in tough however long the distance is, but a wise man should know when to put down his phone.

经过了为期两天的统计学实验,主要通过EXCEL这个软件来完成这次的实验。

首先掌握用EXCEL进行数据的搜集整理和显示,要求熟练运用EXCEL搜集数据,统计分组,制作统计图。这是最基础的操作,让我们首先对EXCEL有一个初步的了解和认识。

实验二是用EXCEL计算描述统计量,可以运用函数描述统计量。要求我们掌握基础的常用的函数对数据进行初步归纳,了解统计学中最常用的函数组成。实验三用EXCEL进行时间序列分析。首先是测定增长量和平均增长量,然后计算出长期趋势。得出我们所要统计的结果的一个预计变动趋势。让调研人员有一个机动的应变对策。这个实验特别主义对时间序列的把握,常常会搞错要除去的年数。这在实验中常常出错。

实验四用EXCEL进行指数分析,指数分析是统计学中最主要的一个数据分析。先计算出总指数,再得出平均指数,最后进行因素分析。其中平均数是通过加权算数平均法得来的。

实验五是用EXCEL进行相关与回归分析。用EXCEL进行相关分析有两种方法,一是利用相关系数函数,在EXCEL中,提供了两个计算两个变量之间相关系数的方法,CORREL函数和PERSON函数,这两个函数是等价的,实验中我运用了用CORREL函数计算相关系数来进行对数据的分析。另一种是利用相关分析宏。EXCEL进行回归分析同样分函数和回归分析宏两种形式,其提供了9个函数用于建立回归模型和预测。这9个函数分别是:INTERCEPT返回线性回归模型的截距、SLOPE返回线性回归模型的斜率、RSQ返回线性回归模型的判定系数、FORECAST返回一元线性回归模型的预测值、STEYX计算估计的标准误、TREND计算线性回归线的趋势值、GROWTH返回指数曲线的趋势值、LINEST返回线性回归模型的参数、LOGEST返回指数曲线模型的参数。在实验过程中我使用的是回归分析宏进行回归分析。

实验六是用EXCEL进行预测。主要有移动平均法、指数平滑法、趋势预测法。在实验过程中分别对这三种方法进行了尝试。都得到了预期的结果。实验七是用EXCEL进行参数估计和假设检验。主要掌握了解Z检验的操作步骤。

通过这次实验让我对统计学的知识框架有了更深一步的了解,并知道通几种常见的基础的方法,对搜集的资料进行数据归纳,抽样分析,并进行预测,对比这个统计学的过程有了进一步的掌握。在今后的学习生活中,希望可以通过这次学习到的方法和知识,可以对自己所研究的领域,进行进一步的调研,分析,使数据更趋于有用化,可操作化,尽量减少数据的赘余与资源的浪费。学习了统计学就要将之灵活运用于实际的生活中去,让知识造福于人类,让知识拥有自己的生命了。

考研英语名师作文预测统计【六】

Recently, there is a popular saying: the world is so large that I want to have a look! As more and more people travel around during their holidays, tourists have brought large sum of money to the local people.

However, too many tourists also bring some problems to the local life. The most serious problem is the pollution caused by the uncivilized tourists. It’s reported that there were thousands of tons of rubbish left after the flag-raising ceremony on Oct. 1st. The uncivilized tourists left their rubbish wherever they go, polluting the local environment. Another problem is the traffic jam caused by so many tourists.

Tourist can promote the economic development of the local areas, but the pollution caused by those uncivilized tourists has brought severe problems. The local tourist authority should set up relative laws to protect the environment of the local areas, and every tourist obey the laws and help to make the places of tourist more beautiful!
