PPT-MEASUREMENT UNCERTAINTY Dr A

A KHINE DIVISION OF CHEMICAL PATHOLOGY NHLS TYGERBERG STELLENBOSCH UNIVERSITY Laboratory Management workshop 36 June 2019 MEASUREMENT UNCERTAINTY is a parameter associated with the result of a measurement that defines the range of the values that could reasonably be attributed to the measured quantity UKAS. Phys. Accuracy and Precision. The . accuracy. of a measurement tells you how close the measurement is to the “true” or accepted value. .
