1、Unit Twelve Data CommentariesIn this unit you will learn how to write a data commentary.数据分析是反映一项研究的过程及结果并将其研究对外公布的材料,是课题研究成果的重要表现形式。数据分析是论文中独立存在的部分,通常置于报告、论文的结论或讨论中。其主要目的是陈述实验结果,分析原因,讨论其重要性及影响。数据分析的呈现和分析应有逻辑性,也就是说,应对数据进行分析及评估,而不是仅止于单纯的表述。数据分析的主要要素包括:1.数据陈述展示论文图表数据资料,并对其进行总结性陈述。2.重点论述通过数据,推测趋势、规律,去粗
2、存精,确定重点。Task Objective3.总结评论通常需要给予解释及预测可能的结果,也需表明意外之结果或不尽如人意的数据,可预测日后研究方向或发展态势。撰写数据分析应注意的几个问题:1.数据分析的常规目的是强调结论,通过现行数据评估通用的理论、广为接受的理念及常理,比较及评估不同的数据集,依照相关方法论来评估数据的可靠性,讨论数据的结果。2.数据资料涉及表格、图标、图表及其他相关的数据,数据资料通常需要进行汇总分析。Read Sample 1 and fill the blankTask Preparation 1Summary statementHighlighting stateme

5、showed negative values of S-PF,which is irrational and proves that the variability of the method can be greater than the actual value of S-PF.Read Sample 2 and answer the questions.Task Preparation 21.What is the summary statement?2.Which sentence is highlighting statement?3.What is the discussion?1
6、.What is the summary statement?2.Which sentence is highlighting statement?3.What is the discussion?KeyWe can see from Figure 7 that the yaw rate of the controlled vehicle is very close to the reference signal.It is known that vehicle yaw rate control improves the vehicle path-following performance.w
