A Study on economically optimal Determination of the Parameters of the Stratified Random Sampling

확률추출에 의한 층별 샘플링의 경제성에 관한 연구

In stratified random sampling a simple random sample must be taken in each stratum to reduce the maximum gain in precision given the minimum cost. The purpose of this paper is to deal with the propertics of the estimates and variances and obtain the economic design of stratified random sampling through the optimum allocation of the sample sizes. In addition, the between stratum variation and the within stratum variation is stratifying the population are described.
