The aim of the randomized response (RR) technique is to decrease social desirability
bias, thus guaranteeing confidentiality, improving respondent cooperation,
and obtaining reliable estimates. This technique obtains stronger estimates
of sensitive characteristics, compared to direct questioning, by reducing respondents
motivation to report falsely their attitudes. In this paper, we have considered
the problem of estimation of variance of an estimator based on an RR
survey data obtained from a complex survey design by using resampling techniques.
The performance of the proposed jackknife modified estimator is tested
by simulation studies. The simulation studies reveal that there is a decrease
in the relative bias and the relative mean square error for all RR schemes. An
RR survey was conducted to investigate sensitive behaviors such as cheating in
exams and bullying. The application of the new jackknife confidence intervals
revealed substantial increase in high-tech cheating and bullying in the university
campuses.
