To assess the seriousness of a high error rate in claims, which type of sample should be pulled?

The correct answer is a discovery sample. A discovery sample is specifically designed to identify and assess the extent of errors or issues present within a particular dataset, such as claims. It is often used in the early stages of an assessment when the goal is to gain insight into the prevalence or seriousness of a problem without extensive resources or time commitment. This type of sample allows organizations to quickly identify areas of concern, which is essential when responding to issues like a high error rate in claims.

In contrast, a probe sample typically involves a limited review of specific cases to investigate known concerns rather than assess the overall extent of an issue. A full statistical sample employs rigorous statistical methodology to achieve reliable and generalizable results, but it may be unnecessary if the primary goal is just to gauge the seriousness of an error rate quickly. A situational sample, while useful in certain contexts, does not specifically focus on determining error rates and their severity.
