数据的分析属于“统计与概率”领域,主要学习分析数据的集中趋势和离散程度的常用方法.近年来,中考考查本章相关知识的比重逐步加大,一方面考查了数据分析的基础知识和思想,另一方面考查了学生运用数学知识的能力和意识.为帮助学生将统计的概念、方法与原理统一到数据处理的活动过程中,进一步 The analysis of data belongs to the field of “Statistics and Probability”, and mainly studies the common methods of analyzing the central tendency and discretization degree of data.In recent years, the proportion of related knowledge in this section has gradually increased, on the one hand, the basic knowledge of data analysis has been examined And thought, on the other hand examined the ability and awareness of students to use mathematical knowledge.To help students integrate the concept of statistics, methods and principles into the data processing activities, further
