Abstract :
In this paper, we have proposed an estimator of finite population mean in stratified random sampling. The expressions for
the bias and mean square error of the proposed estimator are obtained up to the first order of approximation. It is found that
the proposed estimator is more efficient than the traditional mean, ratio, exponential, regression, Shabbir and Gupta (in
Commun Stat Theory Method 40:199–212, 2011) and Khan et al. (in Pak J Stat 31:353–362, 2015) estimators. We have
utilized four natural and four artificial data sets under stratified random sampling scheme for assessing the performance of
all the estimators considered here.
