Abstract :
In this chapter suggests dual to ratio-cum-product type exponential estimator in stratified random sampling. In fact, Srivenkataramana (1980) transformation has been used on Tailor and Chouhan (2013) estimator. The bias and mean squared error of the suggested estimator have been obtained upto the first degree of approximation. The suggested estimator has been compared with usual unbiased estimator in stratified random sampling, combined ratio and product estimators, dual to combined ratio and product estimators, Singh et al. (2008) ratio and product type exponential estimators and dual to ratio and product type exponential estimators given by Tailor et al. (2013). An empirical study shows the performance of the suggested estimator.

Key-Words / Index Term :
Population Mean, Ratio and product estimator, Correlation coefficient, Bias , Mean squared error.
