Singh (1999) suggested a safe randomized response technique to deal with quantitative sensitive characters through Moors ' (1971) strategy, but the variance and percent relative efficiency of the estimator of population mean seem to be incorrect. This note corrects them, and finds Singh 's strategy is superior to Greenberg et al. (1971) strategy in the sense of having smaller variance.
