Connected finite population sampling plans

H. P. WYNN

Department of Mathematics, Imperial College London

Plans for sampling a finite population without replacement are called disconnected if the population separates into twodisjoint sets such that a sample cannot contain units from both sets. It is shown that disconnected plans can achieve, under certain conditions, a maximum variance for the Horvitz-Thompson estimator not achieved by connected plans. Under these conditions simple random sampling is minimax. No plan, however, gives uniformly minimum variance.

Key Words: Block design • Connectivity • Finite population sampling • Minimax • Probability proportional to size
