The present work deals with the problem of estimation of finite population median at current occasion, in two occasion successive (rotation)
sampling. A class of estimators has been proposed for the estimation of
population median at current occasion, which includes many existing
estimators as a particular case. Asymptotic properties including the
asymptotic convergence of proposed class of estimators are elaborated.
Optimum replacement strategies are also discussed. The proposed class
of estimators at optimum condition is compared with the sample median estimator when there is no matching from the previous occasion as
well as with some other members of the class. Theoretical results have
been justified through empirical interpretation with the help of some
natural populations.
