解与统计图有关的信息题,关键在于要看懂统计图,并熟悉实际情景中的数量关系,将统计图信息与实际数据转化为相应的数学问题.请看下面几例. 例1 2003年我国遭受到传染性疾病非典型肺炎(SARS)的巨大灾难,全国人民万众一心,众志成城,抗击“非典”.图1(1)是根据A市某中学“献爱心,抗非典”自愿捐款活动中学生捐款情况制成的条形图,图1(2)是该中学学生人数比例分布图,该校共有学生1 450人.
The key to solving information problems related to statistical charts lies in understanding the statistical charts and familiarizing themselves with the quantitative relationships in the actual scenarios, transforming the statistical map information and actual data into corresponding mathematical problems. Look at the following examples. Example 1 2003 Our country has suffered from the great disaster of SARS. The people of the whole country are united and united to fight against SARS. Figure 1(1) is based on the voluntary donation from a secondary school in A City. The bar chart made by the situation, Figure 1 (2) is the proportion of the student population distribution map, the school has a total of 1 450 students.
