In this research paper, we have developed an efficient estimator by introducing the linear combination of deciles arithmetic mean and coefficient of kurtosis as auxiliary information to achieve efficiency of the estimator for the estimation of population variance. The bias and mean square error has been derived up to the first order of approximation. The empirical study has been carried out through numerical demonstration to justify the performance of new developed estimators.
Key words: Deciles arithmetic mean, Coefficient of kurtosis, Bias, Mean Square Error, Efficiency.
