Acceptance sampling is the examination of a random sample from a population, to see if the number of issues found would allow the population from which it is drawn to be accepted. This approach does not measure the relative quality of a population. Instead, it represents a decision to accept or reject a population. This approach is useful in auditing, since it allows an auditor to draw conclusions about the veracity of the documents in a population without having to spend an excessive amount of time examining each one.
Acceptance testing can result in incorrect conclusions if it is conducted improperly. The quality of the test can be improved by increasing the sample size and averaging the results of several tests.
