Evaluation of a test's bias and imprecision uses several calculations. Although UnityWeb™ performs these calculations, it's useful to understand the calculations, which include:
Mean
Standard Deviation (SD)
Calculating a Control Mean and Range
Standard Deviation Index (SDI)
Bias
Coefficient of Variation (CV)
Determining an Acceptable CV
Coefficient of Variation Ratio (CVR)
Total Error (TE) and Total Allowable Error (TEa)
z-score
Basic QC Statistics
