摘要

In this paper, classic sampling theories, total probability formulae and properties of variance were applied to deduce formulae for the estimate of the population proportion and its estimated variance of the improved RRT model used for dichotomous sensitive question survey in stratified two-stage sampling. The deduced formulae were applied to a survey of premarital sex among college students successfully.
