In this study, we propose exponential ratio estimators in the stratified two-phase sampling
utilizing an auxiliary attribute. The expressions for the mean squared error of these …

Occupational health and safety management (OHSMS) systems are recognised
internationally as highly flexible and can be tailored to all sizes and types of businesses to …

The distribution function (DF) is a determinant functional parameter in many academic
disciplines that use probability tools for data analysis, such as economics and medicine …

In this article, we propose an improved estimator for finite population variance based on
stratified sampling by using the auxiliary variable as well as the rank of the auxiliary variable …

For maximum precision in population parameter estimation under the Stratified sampling
design, the optimum strata boundaries (OSB) could be constructed based on a continuous …

The presence of extreme events gives rise to outrageous results regarding population
parametersand their estimates using traditional moments. Traditional moments are usually …

The aim of this paper is to develop more effective methods for estimating population means
in sample surveys using auxiliary attributes. To achieve this goal, we introduce a modified …

In this article, we suggest an enhanced estimator for the estimation of finite population
variance using twofold auxiliary variable under stratified random sampling. The numerical …

This study introduces some modified classes of estimators of population variance in simple
random sampling utilizing information on auxiliary attribute which cover traditional mean …

Median ranked set sampling is a sampling procedure used to estimate the population mean
when the variable of interest is difficult or costly to measure. Two estimators for the …
