Estimation of Population Variance for a Sensitive Variable in Stratified Sampling Using Randomized Response Technique

Abstract

In this paper, Randomized Response technique (RRT) is used to propose some separate and combined variance estimators for a sensitive variable using stratified random sampling. The performances of the proposed estimators are examined using a unifed measure of respondent privacy and estimator efficiency.
