Feature Discovery and the Sampling Requirements of Archaeological Evaluations

Abstract

AbstractFeatures are important deposits whose density and distribution pose acute sampling problems for archaeological investigations. Excavation is inherently a sampling process, but the ability of excavation samples to meet two important criteria—discovery of features and precise estimation of their frequency—rarely is assessed and often is doubtful. Combining archaeological data on feature density and distribution from Midwestern U.S. sites with appropriate statistical theory, this paper shows that conventional sample standards often are inadequate to meet the criteria. This failure has grave implications for the preservation and management of archaeological sites.
