Glossary Term
A measure of the range of values in a set of numbers. Standard deviation is a statistic used as a measure of the dispersion or variation in a distribution, equal to the square root of the arithmetic mean of the squares of the deviations from the arithmetic mean.
Glossary Term
A statistical method of partitioning a sample of data into subsets such that the analysis is initially performed on a single subset, while the other subsets are retained for subsequent use in confirming and validating the initial analysis.
Glossary Term
Validation evidence that an assay detects the range of variants, genotypes, or serotypes it claims to cover. For evolving targets such as influenza or SARS-CoV-2, inclusivity statements carry a validation date and should be checked against circulating variant lists at procurement time.
Glossary Term
How close amplification is to ideal doubling each cycle, reported as a percentage or derived from the standard curve slope. Efficiency near 90–110% with a linear standard curve supports quantification claims; it is a standard checklist item when auditing assay validation dossiers.
Glossary Term
The act of validating; finding or testing the truth of something.
