Abstract: In large scale surveys, sampling frames are mostly incomplete. Hence, in the present paper, methods of estimation of total population, mean, variance have been developed and the formulae for estimators from incomplete frames in case of SRSWOR and SRSWR are derived. The theory has been substantiated through a numerical problem. This example clearly reveals that estimates are much improved.
Keywords: Simple random sampling, estimation, incomplete frame
