英语作文折线统计图【一】

It was a sunny day. We decided to have a picnic outside the city. In the morning, we took an early bus to Nanhui. It was quite a colorful world. there were GREen trees, orange leaves,red peach blossoms.

At noon, we reached the place, we sat by the river bank and took out a lot of things, such as bread, orange juice, apples, cakes, eggs and so on.But all of a sudden, it began to rain. Unluckily there was no shelter nearby. We had to take a bus to go back home in a hurry.

What an unforgettable picnic it was!

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。

Boys and girls,attention,plealse. I have something to tell you . We are going to have a picnic at Dongshan on the coming saturday.You are asked to bring your own water and food by yourselves because there is no store there. Do remember to put on your sport shoes because we will climb the moutain after lunch.At last, we will get together at half past six at the gate of our school.It takes us 2 hours to get there.

Do be late please! thank you very much!

The picture shows us a dialogue between a father and a son. The son told his father, “Dad, I’m a bit worried about disposing of nuclear waste”. While his father told him, “If you can empty the dustbin here you can do anything”. It reveals the importance of doing small things well before undertaking something big. There is also an old Chinese saying to go with this that a person can’t sweep the world before he can sweep his own room.

I agree on the point that it is of great importance for a person to do small things well before undertaking something big. First of all, doing small things well entail the qualities that needed in doing great things such as patience and ability of controlling time. For example, when we sweep our room, we need to manage our time and energy reasonably. Accordingly, if we sweep a bigger room, for example, a classroom with our classmates, we should learn how to cooperate and allot assignments as well. And a big advantage is that we can draw useful lessons from the failure of performing well because they didn’t cost a lot.

In another word, though these things seem trivial, they reinforce our manipulative ability and thus our understanding to the world. Therefore, we should not ignore the small things.

??胎英语看图作文

二胎政策是今年后半年国家放开的新政策。yuwenmi小编整理了相关的范文,欢迎欣赏与借鉴。

Today, I'm going to talk aobut a change to China's population policy.

今天我将来说一下中国的人口政策改革。

China introduced one-child policy in the late 1970s. This policy has been credited with helping to control China's population growth.

中国在20世纪70年代末推行了独生日子女政策。这一政策被认为可以帮助控制这个国家的人口增长。

It's also been criticized for forcing parents to make difficult personal choices, or in some cases face huge fines.

批评者认为该政策迫使父母做出艰难的个人抉择,或甚至有时候面临巨额罚款。

According to a statement issued on October 29th,2015 by the Communist Party of China Central Committee, China further relaxed its more than three-decade-old family planning policy. The statement said the country's aging trend would be actively addressed by the universal two-child policy.

2015年10月29日,中共中央委员会发布公报称,中国将进一步放开实施了30多年的计划生育政策。“全面二孩政策”将有效应对人口老龄化趋势。

Additionally, From my personal view, One reason for the change, economics. In China, many people care for their elderly relatives, so a single child could end up being financially responsible for parents and grandparents. This new policy could help with that.

改革的其中原因之一是经济方面。在中国,很多人都需要照顾上了年岁的.长辈亲戚, 所以一个孩子最终可能会对父母和祖父母的财务负责。而新出台的政策就可以在这方面起到作用。

Another reason, China wants to improve human rights by the universal two-child policy.

另一个原因是中国希望通过全面二胎政策来改善人权。

本学期我们学了统计学这门课程,通过一学期的学习我们对统计学应用领域及其类型和基本概念有了一个基本的了解,掌握了数据的收集、展示、分析的技术。同时学校也安排了我们学期末统计分析实习,是希望通过这次实习提高我们动手操作的能力和把理论应用到实践中去的思想,也通过实习加深我们对课本上理论的认识和掌握。

这次实习中我们不仅复习巩固了统计学的理论知识,我们也收获了很多新知识,同时通过分组实习也锻炼了我们团结协作的能力,给我们的感触良多。

统计是处理数据的一门科学,统计学是收集、处理、分析、解释数据并从数据中得出结论的科学,统计方法是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。随着社会经济和现代科学的发展,统计理论、方法和应用进入了一个全面发展阶段。一方面,统计学受计算机科学、信息论、混沌理论、人工智能等现代科学技术的影响,新的研究领域层出不穷,如多元统计分析、现代时间序列分析、贝叶斯统计、非参数统计、线性统计模型、探索性数据分析、数据挖掘等。另一方面,统计方法的应用领域不断扩展,几乎所有的科学研究都离不开统计方法。应为不论是自然科学、工程技术、农学、医学、军事科学,还是社会科学都离不开数据,要对数据进行研究和分析就必然用到统计方法,现在连纯文科领域的法律、历史、语言、新闻等都越来越重视对统计数据的分析。

这次统计分析实习,我们组选择的公司是七匹狼。在实习中我们运用数据的搜集、数据的图表展示等理论以及运用EXCEL软件对数据进行处理、分析、解释完成了本次实习的任务。我们搜集七匹狼有关股票的数据信息有每股收益、每股净资产、净资产收益率、主营业务收入、净利润、利润率、每股公积金、每股未分配利润、每股现金流量等。通过对这些数据的整理、分析和总结,我们可以了解七匹狼公司的业绩、经营状况、财务状况和预测未来的发扎趋势等相关信息。

我们学习统计学和进行本次实习活动的目的是运用统计思想进行分析的能力,在实践工作中,要善于利用统计的思维方式进行思考,在纷繁复杂的社会实践中,要学会发现数字、分析数字,并使用数字说话;掌握基本的统计方法,要掌握统计工作中涉及到基本统计概念和基本统计计算方法,能够阅读常规的统计报告,了解统计指标的含义。同时,能够自己处理常见的统计问题;锻炼统计计算的能力。在掌握统计方法的基础上,要培养动手计算的能力。其中涉及到运用数学公式和使用计算机进行计算的有关技能。

在本次的实习活动中我们所收获知识较多既有学习中的也有生活中。在学习中我们将自己所学的知识应用于实际的操作中,理论和实际是不可分的,在实践中我的知识得到了巩固,解决问题的能力也受到了锻炼。本次实习还开阔了我的视野,使我对统计在现实中的运作有所了解,也对统计也有了进一步的掌握,还学习了统计科研网站的制作及为网站建设搜集材料。在生活上我和同学团结协作,相互配合,相互了解,我们彼此相处更加融洽。

我们这次实习时间较短,只是短短的一个星期。我们所学到的知识相对来说还是少之又少的,因此,在以后涉及到日常的自我训练,要学会自己运用计算机等工具,处理统计计算问题。同时,我们以后无论是在学习知识上,还是实际运用上都要永无止尽的学习运用统计学知识。
