Statistical Sampling Overview and Principles
... As stated earlier, sampling is used when it is not administratively feasible to review every sampling unit in the target universe. In practice, sample sizes may be determined by available resources. That does not mean, however, that the resulting estimate of overpayment is not valid as long as prope ...
