Randomized response
From Wikipedia, the free encyclopedia
Randomized response is a research method used in structured survey interview. It was firstly proposed by S.L. Warner in 19651, and later modified by B. G. Greenberg in 19692. It allows respondents to respond to sensitive issues (such as criminal behavior or sexuality) while remaining confidentiality.
