Stratified Cluster Sampling and Its Application on Warner Model for Sensitive Question Survey

摘要

To explore scientific sampling methods and corresponding formulas for sensitive question survey on stratified cluster sampling. Cochran W.G.’s sampling theories, Warner model, total probability formulas and properties of variance were used in this paper. Formulas for the estimate of the population proportion and its variance on Warner model in cluster sampling and stratified cluster sampling were deduced. With high reliability, our survey methods on Warner model may have an extensive application in sensitive question survey.
