Abstract In this article, four ratio estimators designated as simple, Quenouille's, Beale's and modified ratio estimators are compared with respect to bias, efficiency, approach to normality and computational convenience. They are shown to be asymptotically minimum variance bound estimators. Some additional ratio estimators are discussed briefly and compared with these. Quenouille's, Beale's, and modified ratio estimators are found to be more attractive than the alternatives compared.
