Webb3.3.1 Definition of Systematic Errors Systematic errors of a titration are for example disturbing influences due to the method itself or to solvent blank values. In the linear regression according to chapter 3.3 systematic errors show up as a significant deviation of the y-axis intercept a of the regression line from the zero point coordinates (see WebbDefinitions Summary Systematic errors: - An error that is repeated throughout the course of an experiment is said to be a systematic error. These may be due to inaccuracy in the apparatus, or in the techniques applied. Precision:- This refers to how close the measured values are to one another. Readings may be very precise, but wildly inaccurate.

WebbRandom Error is unpredictable, and it occurs due not to know sources. In contrast, the systematic error is predictable and occurs due to a defect of the instrument which is used for measurement.
