Two sampling schemes using auxiliary variables for cluster sampling (CAS or CBS system) have been proposed. In one of the schemes, the auxiliary variable is used in selecting the clusters whereas in the other the elements within the clusters are selected using the auxiliary variable. The efficiencies of the proposed sampling schemes as compared to the conventional cluster sampling with equal probabilities of selection as well as SRSWOR have been worked out empirically for natural as well as constructed populations. It has been observed that for the types of population considered for comparison the performance of the sampling scheme utilising auxiliary variable in selecting elements within clusters is the best of all the sampling schemes considered for comparison.
