The document discusses the efficiency of cluster sampling in surveys conducted on two occasions, highlighting its cost-effectiveness and the conditions under which it outperforms simple random sampling. It presents a generalized estimator for population means, analyzes the variance of this estimator, and compares the relative efficiency of cluster sampling to simple random sampling using various parameters. The findings suggest that cluster sampling can provide more efficient estimates, particularly when in
