Abstract: In this paper a three phase stratified sampling is proposed to estimate the population mean of character by a three phase stratified regression estimator and some numerical results are presented to illustrate efficiency of the proposed procedure against possible alternative ones. The expected cost optimum sample sizes on first, second and third phases are also calculated.
