What is systematic uncertainty? A source of measurement uncertainty caused by repeatable imperfections in the experiment. A source of measurement uncertainty caused by unknown and unpredictable changes in the measuring instruments or environmental conditions. The approximated spread in a measured set of data. The difference between a measured value and a predicted value.
