Multiple choices sensitive questions survey in two-stage sampling and its application
Objective To explore scientific sampling methods and corresponding formulas for multiple choices sensitive questions survey with the sample selected by two-stage sampling. Methods Randomized response technique (RRT) of multiple choices sensitive questions and two-stage sampling were showed in this paper. Moreover, sampling theories, total probability formulas and properties of variance were used. Results Formulas for the estimator of the population proportion and its variance on randomized response model of multiple choices sensitive questions in two-stage sampling were deduced. Our survey methods and formulas on the RRT model have a successful application for multiple choices sensitive questions survey, what students of Soochow University cheated in exams. The severity of cheating in exams was classified into three types and the proportion was 68.066％, 18.072％ and 13.861％ respectively. Conclusion The methods and corresponding formulas on multiple choices sensitive questions survey with the sample selected by two-stage sampling were feasible.
