Correct Value: A quantity that has been proven or generally accepted as being valid. It can be a standard measurement for an item used in testing measurement systems. Or, a known value that is correct on a theoretical basis, such as the circumference of a circle.

How To Measure Accuracy and Precision in 5 Steps

WebMar 29, 2024 · Researchers are familiar with accepted values. The observed precise and accurate values are determined during the research, which is expressed as a percentage. Accuracy is obtained by subtracting the observed value from the accepted value or dividing the observed value by the accepted value and multiplying the quotient by 100. WebFor example in using the measurement uncertainty: >> at 25.02 grams UUC reading, we are 95% confident that the true value or true reading of the UUC falls within the range of 25.0107 to 25.0293 (25.02+/-0.0093)- The measurement uncertainty range shows the possible locations of the true value of the UUC result.
