The problem of estimating the variance of a finite population is an important issue in
practical situations where controlling variability is difficult. During experiments conducted in …

One of the disadvantages of the point estimate in survey sampling is that it fluctuates from
sample to sample due to sampling error, as the estimator only provides a point value for the …

This article presents a new set of estimators designed to estimate the finite population
variance of a study variable in two-phase sampling. These estimators utilize the information …

In this paper, we consider the improved estimation of average production of peppermint at
block level of Barabanki district of Uttar Pradesh State (India). We suggest certain estimators …

This article suggests an improved class of efficient estimators that use various
transformations to estimate the finite population variance of the study variable. These …

To estimate the finite population variance of the study variable, this paper proposes an
improved class of efficient estimators using different transformations. When both the …

In this research paper, an improved set of estimators for finding the finite population variance
of a study variable under a stratified two-phase sampling design is introduced. These …

This paper aims to investigate the impact of transformed auxiliary variables on the
performance of variance estimators of finite population under adaptive cluster sampling …

In this paper, we introduce a new, improved family of estimators aimed at improving the
accuracy of finite population variance estimation. The proposed class of estimators is …

The use of extreme values of the auxiliary variable is sometimes more beneficial to get the
high efficiency of the estimators, and the study variable can have a correlation with the rank …
