Measurement uncertainty

Measurement uncertainty refers to the degree of doubt or variation in a measurement result. It recognizes that no measurement is perfectly exact due to factors like instrument limitations, environmental conditions, or human error. Essentially, it provides a range within which the true value is likely to lie, expressed with a certain level of confidence. This helps ensure that measurements are interpreted accurately and consistently, acknowledging the inherent imperfections involved in collecting data. By understanding uncertainty, we can better assess the reliability of measurement results and make informed decisions based on them.
