近似法和精确法随机抽样的 SPSS 实验研究

摘要

为了解SPSS 近似法随机抽样与精确法随机抽样的抽样效果，通过实例研究，将用两种随机抽样方法所得抽样数据进行分析，使用点估计值对两种抽样方法进行比较。在不需要精确样本含量的前提下，采用SPSS的近似法随机抽样会更加方便、实用。%To study the effect of random sampling method which approximately sample and exactly sam-ple in SPSS .The empirical research was used ,the data obtained by the two random sampling method were analyzed .The point estimation method was used to compare different data .The approximately sample will be more convenient and practical when the sample size was not necessarily .
