“统计和概率的简单应用”是苏科版初中数学的收官之作,它对整个初中阶段的统计和概率知识起着统领的作用.我们知道:概率研究随机现象的规律性,统计则研究如何合理收集、整理、分析数据,并从数据中获取信息,它们都可以为人们决策提供依据和建议,而其中蕴含的统计思想和概率观点更是其灵魂.在本章,我们学习了以下6小节内容:中学生的视力情况调查、货比三家、统计分析帮你做预测、抽签方法合理吗、概率帮你做估计、收取多
“The simple application of statistics and probability” is the conclusion of the junior high school mathematics of Suke Edition, which plays a leading role in the statistics and probability knowledge of the entire junior middle school.We know that the regularity of stochastic phenomena in probability research, statistics We study how to collect, organize, analyze data and obtain information from the data reasonably, all of which can provide the basis and suggestion for people’s decision-making, and the statistical ideas and probability opinions contained therein are the soul.In this chapter, we study the following 6 sub-sections: visual acuity secondary school students survey, shop around, statistical analysis to help you make predictions, lottery method is reasonable? Probability to help you make estimates, charge more
