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 (DQ), by reducing respondents motivation to falsely report their attitudes. In this paper, we have considered the problem of estimation of variance of an estimator based on a 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 randomized response schemes. A randomized response 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.
