Therefore, we need to give some indication of the reliability of measurements and the uncertainties in the results calculated from these measurements. . An Introduction to Uncertainty Analysis. Error Sources. The measurement process consists of three dis-tinct steps: calibration, data acquisition, and data reduction. calibration error. data acquisition error. Accuracy vs. Precision.

Quality of a Measurement. “Give or Take”. 1.2 – Uncertainties and errors. Essential idea:. . Scientists aim towards designing experiments that can give a “true value” from their measurements, but due to the limited precision in measuring devices, they often quote their results with some form of uncertainty.. 1. Needed because total variance of process recorded is the sum of process variation and measurement variation. Thus, when there is a special cause, always look first at measurment tool. 2.
