《数学课程标准》(2011版)指出:了解在现实生活中有许多问题应当先做调查研究,收集数据,通过分析做出判断,体会数据中蕴涵着信息;了解对于同样的数据可以有多种分析的方法,需要根据问题的背景选择合适的方法;通过数据分析体验随机性,一方面对于同样的事情每次收集到的数据可能不同,另一方面说明只要有足够的数据就可能从中发现规律。一、精心设计实践应用活动,感受数据分析的现实意义【案例一】统计同学们的身高、体重、生日、爱吃的水果,统
The Mathematical Curriculum Standard (2011 Edition) states: To understand that there are many problems in real life, research should be done first, data collected, and judgments made through analysis, and the information contained in the data should be understood. There are many ways to understand the same data The method of analysis needs to select the appropriate method according to the context of the problem. By analyzing the randomness of data analysis, on the one hand, the data collected for each and every same event may be different, and on the other hand, the law may be found as long as there is enough data . First, elaborate practical application activities, experience the practical significance of data analysis 【Case 1】 Statistics students’ height, weight, birthday, favorite fruit,
