摘要
在网络科技与大数据迅猛发展的今天,非概率抽样有了更广泛的应用空间。非概率抽样主要是解决总体单元难以分辩的抽样问题。而抽样结果估计是否准确可信一定程度上依赖于样本量的确定。主要阐述了非概率抽样在精度、调查费用与损失的要求下确定样本量的方法。
With the rapid development of Internet technology and big data, there is a wider application space for non-probabilistic sampling. It mainly solves the sampling that the overall unit is difficult to distinguish. However, the estimation of the sample results depends on the determination of the sample size. The method of determining the sample size of non-probability sampling in accuracy,investigation cost and loss is described.
