Abstract: A survey was conducted on the students of a certain University to determine the prevalence of various risky behaviors. The data was collected using direct method (DR) and randomized response (RR) method. It is found that RR method yielded higher estimates of the prevalence. The estimated standard errors based on RR surveys did not always produce expected results that the estimates should be higher than that of the DR surveys.
