Cluster Sampling,he sampled units (farmers) being scattered all over the region. This will require a good amount of travel to reach all the selected farmers for collecting information about the indebtedness and will, therefore, involve a formidable amount of travel expenditure.

Multistage Sampling,mber of units in the sample, greater precision can be attained if (1) the units are distributed over a larger number of clusters, and (2) instead of completely enumerating all the units in each selected cluster, only a sample of units is observed. This logic gives rise to the following definition:

Schmerztherapie bei onkologischen Patienten,In the preceding chapters, we have considered methods of sampling in which successive units are selected at random. In this chapter, an alternative sampling procedure is considered. The scheme, besides ensuring for each unit equal probability of inclusion in the sample, selects the whole sample with just one random number.

Michael Weber,Günter Bock,Martin Budweg inferences about the population, a procedure that provides a precise estimator of the parameter of interest is desirable. Many sampling schemes have been developed to achieve this objective. To begin with, simple random sampling, the simplest and the most basic sample selection procedure, is discussed.
