概率与统计是高考必考内容,它以应用问题为载体,以解决实际问题为目的。统计涉及内容主要有:抽样、统计图表、频率分布直方图、均值与方差、茎叶图、回归分析等核心考点,可以小题出现,也可以与概率分布列网络交汇构成解答题;随机变量的分布列和期望以解答题为主,常与排列组合、概率以及统计等知识综合命题,凸显概率模型的应用。 Probability and Statistics is the exam content of the college entrance examination, which uses the application of the problem as a carrier, to solve practical problems for the purpose. Statistics include: sampling, statistical charts, histograms of frequency distribution, mean and variance, stem and leaf, regression analysis and other core test sites, can be a small problem, it can also meet with the probability distribution column network to form the answer questions; random variables Distribution columns and expectations to answer the main questions, often with the combination of combination, probability and statistics and other knowledge of the proposition, highlighting the application of probability model.
