我理统计数理统计是数学中联系实际最直接最广泛的学科之一。它应用概率论的方法来研究大量随机现象的统计规律性，方法的主要特征在于，从客观的随机总体中，抽取部分样本，对样本进行数学处理，通过部分数据得到关于整体的充分正确的了解。例如：研究大量产品怎样进行检查， My statistics Statistics is one of the most direct and extensive subjects in mathematics. It uses the method of probability theory to study the statistical regularity of a large number of random phenomena. The main features of the method are that it takes part of the samples from the objective random population, performs mathematical processing on the samples, and obtains the full and correct understanding of the whole through partial data . For example: how to inspect a large number of products,
