ABSTRACT
The single-sampling plan is a basic to all acceptance sampling. The simplest form of such a plan is single sampling by attributes which relates to dichotomous situations, i.e., those in which inspection results can be classified into only two classes of outcomes. This includes go, no-go gauging procedures as well as other classifications, such as measurements in or out specifications. Applicable to all sampling situations, the attributes single-sampling plan has become the benchmark against which other sampling plans are judged. It is employed in inspection by counting the number of defects found in the sample (Poisson distribution) or evaluating the proportion defective from processes or large lots (binomial distribution) or from individual lots (hypergeometric distribution). Single sampling is undoubtedly the most used of any sampling procedures.
