Stratified Two-stage Cluster Sampling on Unrelated 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 stratified two-stage cluster sampling, complex sampling methods, unrelated 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 unrelated question RRT model in stratified 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 unrelated question RRT model in stratified two-stage cluster sampling were proved feasible.
