What if the number of sampling units estimated to yield the required confidence and precision levels is unreasonably large?
When there are few errors in the Probe or Discovery Sample, it is not uncommon for the Full Sample size to be quite large. The reason for this is because, generally, the fewer errors in the sample, the greater the variability of the sample. When the variability is large, the reviewer needs to review more units to reach a reasonable level of confidence and precision. If the provider believes the Full Sample size is unreasonably large, it should contact its OCIG monitor for further guidance.
