统计知识是初中数学中重要的内容,它涉及面广,尤其与现实生活联系密切.统计中常用到许多图表,因为统计图表能把枯燥、抽象的数据描述出来,一目了然,并能获取许多信息,通过观察、整理图表信息,抽象出数学问题,最终解决实际问题.这种题目的信息量大,大多数条件不是直接给出,而是隐含在图象中,解答它不仅要有扎实的数学基础知识,而且要有较强的读图、识图、分析能力.解图表信息题的关键是“识图”和“用图”.下面
Statistical knowledge is an important part of junior high school mathematics, it involves a wide range, especially with the close contact with the real life.Statistics often used to many charts, because statistical charts can describe the boring, abstract data at a glance, and access to many of the information, By observing and arranging chart information, abstracting out mathematical problems and ultimately solving practical problems, the amount of information in this subject is large, most of the conditions are not given directly, but implicit in the image to answer it not only to have solid mathematics Basic knowledge, but also have a strong reading map, knowledge map, analysis capabilities. The key to the solution chart information problem is “knowledge map ” and “use map ”.
