I'm trying to understand what constitutes a bad coefficient of variation. Is there a specific range or threshold that indicates a poor or unacceptable level of variation?

In the realm of method performance evaluation, the coefficient of variation (CV) serves as a crucial metric. A CV of 5% or less often elicits a positive impression, suggesting a high degree of precision and reliability in the method's outcomes.

Conversely, a CV exceeding 10% can evoke a sense of dissatisfaction, as it indicates greater variability and potentially lower method quality. However, it is important to note that the CV alone does not constitute a definitive judgement.

Before arriving at a conclusion about a method's performance based on its CV, it is imperative to consider the mean value. The mean value provides valuable context, allowing for a more comprehensive assessment of the method's overall performance.

For instance, a method with a high CV but an exceptionally high mean value might still be considered acceptable in certain applications, particularly if the variability does not significantly impact the desired outcome.

On the other hand, a method with a low CV but a low mean value may not be suitable for applications requiring high accuracy or precision. Thus, a holistic approach that takes both the CV and mean value into account is crucial.
