Hans-Dieter Görtz,Franz Brümmerol of the final sample size. There have been several suggestions for limiting this final sample size of adaptive cluster samples. In this design, traveling costs are increased because the second phase sample is selected after the first phase sample is completed. In the second phase of the sampling d

Werner Buselmaier,Joana Haussigmethods provide poor estimates of the population mean/total. In such situations, adaptive sampling is useful. In traditional stratified sampling, similar units are grouped a priori into strata, based on prior information about the population. But within a stratum, the population is rare and clumped.

Several suggestions have been made by the different researchers for limiting this final sample size of the adaptive cluster sample. For instance, Salehi and Seber (., .) suggested a two-stage sampling design
