| Abstract: | Abstract： Objective is to provide scientific precision calculating formula of higher random sampling investigation method and statistics for multiple choices sensitive problems, design a multiple choice random sampling model for sensitive question under stratified sampling, calculation formula of estimator and its variance and deduced the overall proportion, to compute confidence in- tervals for the sensitive attribute ratio 95%. Investigation on cheating in the undergraduate student exam of Hunan City University has been achieved high reputation. |
