WHAT IS ACCURACY?
Accuracy is a measure of how close the result is to the real value. It refers to the degree of agreement between a measurement result and an accepted reference value, indicating how well the result represents the quantity being measured.
A measurement is considered accurate when it is close to the reference value, regardless of its repeatability.
HOW TO IMPROVE ACCURACY?
To assess the accuracy of a measurement, it must be compared against a known reference value. This process is known as calibration, and it helps to identify and reduce the systematic errors, ensuring traceability to recognized standards.
Accuracy is closely related to other metrological parameters such as precision, repeatability, and resolution, all of which are essential for scientific and technological measurements. Also, it is important to understand that a measurement could be accurate but not repeatable, repeatable but not accurate, or both.
