Theory of Errors The theory of errors explains different theories that can be used to correct the incorrect observed readings. The theory of errors can be applied weight of observed readings. With the help of different theories, mean errors, most probable errors, etc., can be applied. In surveying, errors can be classified as systematic errors, instrument errors, etc. In surveying works, length, area, etc., need ...

TYPES OF ERRORS Errors of measurement are of three kinds: (i) mistakes, (ii) systematic errors, and (iii) accidental errors. (i) Mistakes. Mistakes are errors that arise from inattention, inexperience, carelessness and poor judgment or confusion in the mind of the observer. If a mistake is undetected, it produces a serious effect on the final result. Hence every value to be recorded in the field must ...

1.4 ERRORS 1.4.1 Errors, Types of Errors Error (Definition) : An error is a fault, which may occur even in the most careful observation. Or Error is a deviation of measurement from standard value. Or error is an uncertainty in a given measurement. Error arises due to human limitations and instrumental limitations. Errors cannot be completely eliminated but can be reduced. (1) ...
