针对抽样检测的两种不同类型—计量抽样和计数抽样,如何解决样本不完备性,即样本与母体的差异,介绍了相关的统计学理论基础,内容包括样本统计参数的随机性和无偏性,解决不确定性,控制错判与漏判概率。
In order to solve the problem of sample incompleteness, that is, the difference between samples and matrices, two different types of sampling - metrology sampling and counting sampling are introduced. The related statistical theory is introduced, including the randomness and unbiasedness of the statistical parameters of samples , To solve the uncertainty, control the wrong judgment and missed judgment probability.
