摘要
数据分析观念是统计的核心词.它有两个核心特征:一是认识到数据蕴含着信息;二是了解数据具有随机性.它还具有缄默知识的一些特性.用数据分析推导结论是一种归纳推理.经过调查分析提出如下几点教学建议:注重数据来源及问题的设计;开展数学活动,体会数据的意义;自己制定标准,提高数据分析方法的鉴赏力;利用数学实验,展现数据的随机性;引导对数据分析的结论的认识.
The concept of data analysis is the statistical core words. It has two core features, one is to recognize the data contains information, the other is to understand the data with random. It also has some of the characteristics of tacit knowledge. By analyzing the data the conclusions derived is a kind of inductive reasoning. After investigation and analysis,we are put forward some teaching suggestions: Pay attention to design data source and problem, developing mathematic activities, experience the meaning of the data; formulate their own standards, improve data analysis method of appreciation; using the experimental mathematics, show the random data; guide understanding the conclusion of data analysis.
