Sample sizes for bioequivalence studies
Statistics in Medicine, 1991AbstractIn recent years a number of decision rules, based on sound statistical principles, have been proposed for deciding if a test formulation is bioequivalent to a reference formulation. The decision rule based on confidence intervals has been accepted by regulatory agencies, at least by the Food and Drug Administration of the United States.

Sampling and Samples in Cross-Cultural Studies
Behavior Science Research, 1976The various samples and sampling universes available to the researcher about to undertake a cross-cultural study are systematically reviewed. Discussed are the Human Relations Area Files, the "World Ethnographic Sample," the Ethnographic Atlas (both the complete atlas as well as the summary version), the Standard Cross-Cultural Sample, the Quality ...

The rarefaction method proposed by Sanders (1968) to allow one to compare the diversity of samples composed of different numbers of individuals and species is compared with the results that would be obtained if smaller random samples were taken from a universe defined by the observed sample. The rarefaction technique overestimates the number of species

Using the example of Ohio and its media markets, this chapter discusses the geographic distribution of respondents resulting from alternative sampling schemes. Traditional survey research designs for gathering information on voter attitudes and behavior usually ignore variability in context in favor of representation of a target population. When sample

Sampling and observational studies.
2000Abstract A census is a count of a population, where every member of the population is studied. For many purposes this is impractical so we use a sample. We want the sample to be representative, i.e. to have the same characteristics as the population.

The feature of a growth study which introduces novel sampling problems is its duration over time. Thus, as well as dealing with the usual problems of human population sampling, we need to consider how to choose sample units to represent different occasions or ages.
