摘要：
This paper discusses the problem of estimation of ratio of two population means in stratified random sampling. In fact, a ratio-cum-product type exponential estimator has been developed for ratio of two population means in stratified random sampling. To compare developed estimator with existing estimators, the bias and mean squared error have been obtained upto the first degree of approximation. An empirical study shows that the developed estimator is most efficient than other estimators.
