Data Rejection Report

The Data Rejection Report is one of the Unity™ Interlaboratory Reports and is only generated when data is rejected by the Unity™ Interlaboratory Program. The rejected data points are not included in cumulative statistics or in statistical comparisons. Data points may be rejected for two reasons:

• The data points are outside the standard statistical range, based on consensus group mean, SD range, or CV.
• The data points were reported with an incorrect code (for example, invalid units, invalid method, and so on).
