## Abstract A class of almost unbiased ratio estimators for population mean Οƒ is derived by weighting sample Οƒ = (1/__n__) Οƒ __y__~__i__~, ratio estimators Οƒ and an estimator, Οƒ (__y__~__i__~/__x__~__i__~). It is shown that NIETO DE PASCUAL (1961) estimator is a particular member of the class and a
