There are situations when we need information on sensitive features/characteristics of the individuals in a population. Usual sampling techniques based on ‘direct’ questionnaire may not be fruitful and are likely to lead to ‘refusal’ or ‘untruthful’ reporting. To overcome such undesirable consequences, randomized response techniques [RRTs, in short] have been introduced and extensively used in real-life situations. We discuss some salient features of this technique.
