Overview
Educational explanation of accuracy and precision as method-performance concepts in analytical measurement.
Purpose
The purpose of this page is to explain the analytical concept in scientific terms and support transparent interpretation of laboratory documentation.
Scientific Principle
Accuracy relates to closeness to an accepted value, while precision relates to consistency among repeated measurements.
How the Method Works
At a conceptual level, these characteristics describe different aspects of measurement performance and should be interpreted within method scope.
What the Method Measures
- Closeness to reference value
- Repeatability or intermediate precision context
- Measurement reliability within method limits
Interpretation Fundamentals
Accuracy and precision support evaluation of analytical confidence but do not remove the need to define scope, matrix, and method conditions.
Limitations
- A precise result can still be biased.
- Accuracy evidence depends on reference quality.
- Performance characteristics are not medical claims.
Quality Considerations
Quality review considers whether reported performance characteristics match the analytical question and are appropriately documented.
Common Misconceptions
- Accuracy and precision are not interchangeable.
- Good precision does not prove identity.
- Measurement-performance education is not procedural instruction.
