Randomized response model
Randomized response is a survey technique used to gather sensitive information from respondents while maintaining their privacy. This model allows participants to answer questions honestly without revealing their true response.
The basic idea of the randomized response model is to introduce randomness into the survey process. Participants are given a randomizing device, such as a coin or a die, which they use to determine how to respond to a sensitive question. For example, if the question is „Have you ever cheated on a test?“, the participant may be instructed to flip a coin and answer „yes“ if it lands on heads and „no“ if it lands on tails.
By adding this element of randomness, respondents can provide truthful answers without fear of judgment or repercussions. The data collected from a randomized response survey can then be analyzed to estimate the true prevalence of sensitive behaviors or attitudes in a population.
Overall, the randomized response model is a valuable tool for researchers looking to gather accurate information on sensitive topics while protecting the privacy of their participants.
