How the samples are allocated to strata or to clusters? Which is the best sampling method? How large a sample size should be? Will the sample provide the precision that we require? How the best results can be obtained at the lower cost? How to design and analyze different forms of sample surveys? The author focusses on using sampling techniques and ideas to solve real problems. This text includes different sampling methods and different sample allocation plans to create the powerful, cost effective survey sample design for your study. It covers a wide range of sampling methods simple random sampling, stratified sampling and cluster sampling. The book also describes the mathematics involved behind the confidence limits, ratio estimation, sample size and survey precision. Small area estimation, randomized response, network, adaptive sampling, control sampling and permanent random numbers are also discussed in addition to most of the classical topics.
