Sampling of Multi-Unit Drug Exhibits

CODEN: JFSCAS

Abstract

The total number of drug exhibits submitted to forensic science laboratories continues to grow markedly, and increasingly, these exhibits are composed of ever larger numbers of units. These facts make the use of a sampling plan, which applies some limitations to the number of units sampled, highly desirable. A sampling plan assumes that the characteristics of the nonexamined units are the same as those in all of the examined units. This paper examines the validity of this assumption by the use of mathematical concepts. Various sampling plans, exhibit sizes, and sample sizes are used as examples. The effect of sample size on quantitative accuracy is also discussed.
