Mõõtmistäpsus

Mõõtmistäpsus refers to the degree to which a measurement conforms to the true or accepted value of the quantity being measured. It is a fundamental concept in metrology and plays a crucial role in scientific research, engineering, quality control, and various other fields. High measurement accuracy is essential for ensuring the reliability and validity of results, making informed decisions, and achieving desired outcomes.

The accuracy of a measurement is influenced by several factors, including the precision of the measuring instrument, the skill and training of the operator, environmental conditions, and the inherent variability of the quantity being measured. Instruments are often calibrated against known standards to minimize systematic errors and improve their accuracy.

Accuracy is distinct from precision, which describes the reproducibility or consistency of a measurement. A measurement can be precise but inaccurate if the instrument is consistently offset from the true value. Conversely, a measurement can be accurate on average but imprecise, with individual readings scattering around the true value.

In practice, achieving perfect accuracy is often impossible due to unavoidable uncertainties in the measurement process. Therefore, metrology focuses on quantifying and minimizing these uncertainties to the greatest extent possible. The reported accuracy of a measurement typically includes a statement of the estimated uncertainty, providing a range within which the true value is expected to lie with a certain level of confidence.
