Abstract

In this article, a chain ratio-type estimator for estimating finite population means under two-phase sampling using systematic sampling has been proposed. The bias and mean square error up to a first-order approximation of the suggested estimator has been derived using the Taylor series expansion scheme. The conditions for which the proposed estimator outperformed other related estimators considered in the study have been established. An empirical study was also conducted to investigate the efficiency of the proposed estimator over some related existing estimators and the results revealed that the proposed estimator is more efficient.
