What does accuracy refer to in scientific measurements?

Accuracy in scientific measurements refers to how close a measured value is to the true or accepted value. This concept is crucial in scientific research because it indicates the reliability of the data collected. When measurements are accurate, they reflect the actual characteristics of the object or phenomenon being studied. A measurement can be precise, showing consistency and reproducibility, yet not accurate if it does not align with the true value. Therefore, a clear understanding of accuracy helps scientists ensure that their findings truly represent the reality they are investigating.
