2016年新SAT考试改革中,题目设计上很大的一个变化就是在文科科目中加入了数据分析的题目,也就是图表类题目,在美国当地时间2016年3月5日的新SAT全球首考中,图表类题目在东海岸麻省和纽约考区出现了多图对比的题目,这个类型的图表题目以往官方的材料中并未出现多图比较的题目,而本次首考真题中,出现通过三个图表,比较K62,K69与earth,及Mars之间的距离哪两个是相等的。题目形式上和以往的看图表完成数据分析有所不同,需要考生对于三张图做出相互对比来进行分析,从而得出相同距离的选项。本次考试的图表题目不仅数量变为多图对比,图表内容也是天文学科的专业信息,本身解题难度并不大,但是需要考生能具备看懂学科图表的能力。
但其实,在图表题目方面,方法还是有迹可寻的,掌握正确的读取图表的方法会帮助我们快速解决图表类难题。下面我们具体分析图表类题目的解题方法。
Quantitative Information题目不仅考察对原文文本的理解,更要求考生对量化的数据信息有较强的读取能力。关于数据图表的理解,需要大家注意以下几点:
阅读题干,清晰理解题干要求;
精读图表标题、批注、介绍等,了解图表数据的内容;
确认横纵轴分别代表什么数值,一定要注意数据的单位;
对应数据和图例,重点关注图例代表的信息;
匹配题干要求,排除法解题。
例如下面这道题:
Today, epidemiology is considered a basic science of public health. It is a quantitative discipline built on probability, statistics, and research methods, a method of causal reasoning based on developing and testing hypotheses, and a tool to promote and protect the health of the public. Examples of applied epidemiology include monitoring reports of communicable diseases in the community; and tracking down the cause of a food-borne outbreak. While many epidemiologists work for health departments at the local and state levels, a number are also employed by colleges and universities. (1)In 2012, the median wage for epidemiologists in the United States was around $60,000, though this number was substantially larger for those working in the state government. For those interested in pursuing a career in this field, the prospects also look bright, but employment is projected to grow 10 percent between 2012 and 2022.
(1)After reviewing the passage and the graph, the writer determines that the statement made in the underlined sentence is not accurate. Which of the following revisions should the writer make to correct the inaccuracy?
Replace $60,000” with “$50,000.”
Replace “$60,000” with “$100,000.”
Replace “state government” with “local government.”
Replace “state government” with “private sector.”
这道题目出错率很高,错误原因并不在于数据的复杂性,而是大多数人没有仔细理解坐标单位的意义。所以解题时我们要重点注意图表的图例、坐标等信息,上面这道题目的横轴percentile表示的是百分点,即在某一百分数数值以内任意可能的数值,故在annual income在60,000的时候,private sector的百分点在25%以下,而Local Government和State Government都在50%~75%之间,明显大于private sector的比例,所以本题目答案D项也就可以轻易选出。在解上面这道题目的时候我们需要注意确认题干要求,重点在于图表数据的解读能力,正确读懂图表的信息,答案用排除法即可得出结论。
