Two-stage Cluster Sampling on Additive Question Model for Quantitative Sensitive Questions

摘要

To explore scientific method and corresponding formulas for quantitative sensitive questions survey with the sample selected by two-stage cluster sampling, complex sampling methods, additive question RRT model, sampling theories and properties of mean were used. The formulas of the estimator of the population mean and its variance for sensitive questions on additive question RRT model in two-stage cluster sampling were deduced. After being employed successfully in a survey of the frequency of cheating in exams among college students at Suzhou University, the method and corresponding formulas for sensitive questions on additive question RRT model in two-stage cluster sampling were proved feasible.
