 ABSTRACT

In this manuscript, an improved estimator for the estimation of population variance is proposed by incorporating the linear combination of Quartiles arithmetic mean, and deciles arithmetic means as auxiliary information. The bias and mean square error are derived up to their first order of approximation. An empirical study demonstrates the performance and justifies the usefulness of the proposed estimators.

Key words: Quartile arithmetic mean; Deciles arithmetic mean; Bias; Mean square error; Efficiency.
