21. Clemence identified systematic errors in the predictions of Mars'path. 22. Thus the variability was thought to possibly be the result of systematic errors in measurement. 23. Systematic errors can sometimes be compensated for by means of some kind of calibration strategy.24. At first it was thought that the declination must be the result of systematic error . 25. To explain this kind of systematic error , the idea of the " interlanguage " was developed. 26. This caused systematic errors resulting in imaginary movements. 27. If the cause of the systematic error can be identified, then it usually can be eliminated. 28. It is also possible for laboratories to have systematic errors , caused by weaknesses in their methodologies. 29. This is very helpful for real-world measurements that can be affected by detector noise and systematic errors . 30. Systematic error is sometimes called statistical bias.
