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.
