You want to design a sampling plan that accepts a particular lot of product at the AQL most of the time. For example, you receive a shipment of microchips, and the AQL is 1.5%. Because you know that you won't always make the correct decision (sampling risk), you set the producer's risk (α) = 0.05.

We use exposure density sampling (EDS) as proposed by Wolkewitz et al. (2009) as an efficient risk set sampling that avoids time

RISK SET SAMPLING 9. 2 and 3. Th e sample size is 200. For eac h scenario, 2000 simulations are con-ducted and Thomas’ estimator and the proposed estimator are calculated. Results.

Aspen Publishers, 2000. Also called “risk set” or “density” sampling of controls who are “currently at risk” This is how sampling risk has happened. ISA 530 Audit sampling that covers that audit sampling, sampling technique, and sampling risks. We recommend reviewing this standard to get a full understanding related to audit sampling. Or you can check this article. Now before we go to sampling risks, let us summary the audit risks so that you can have Se hela listan på academic.oup.com A Stratified Two-Stage sampling design is proposed .Stratification of auditable units is based on risk assessment. Here quantitative risk assessment (score) is proposed.
