统计与概率是近几年中考数学重点考查的内容.统计与概率作为初中数学新课标增加的新内容,经过几年的教学与实践,在命题方面日趋成熟.纵观2008年各地中考数学卷,统计与概率试题约占总分的15%,题型基本为选择题、填空题、解答题,在统计方面主要考查各种调查方式的识别和应用,平均数、众数、中位数、方差的简单计算,在概率方面主要考查一些简单事件发生的概率.
Statistics and Probability are the key contents of the mathematics test in the last few years.Statistics and Probability As the new content added in the new mathematics curriculum standard of junior high school, after several years of teaching and practice, the proposition has matured. , Statistics and probability questions about 15% of the total score, the basic type of multiple choice questions, fill in the blank questions, answer questions, mainly in the statistical aspects of the investigation and identification of various survey methods and applications, the average, mode, median, The simple calculation of variance, in terms of probability, mainly examines the probability of some simple events occurring.
