Measurement errors can be divided into two components : random error and systematic error . 14. This reasoning is not valid if there are systematic errors present in the watches. 15. For two ports there are 12 possible systematic errors analogous to the three above. 16. A common method to remove systematic error is through calibration of the measurement instrument. 17. In science and engineering, a bias is a systematic error . 18. Systematic error , however, is predictable and typically constant or proportional to the true value.19. Interpretation of this passage in Ptolemy is difficult, and it may contain systematic errors . 20. For example, these teams discovered systematic errors occurring with a particular type of intravenous pump.
