Precision and Accuracy
a) Precision depends on the human factor, the level of
understanding of what needs to be
measured. Level of involvement.
Lack of
precision means blunder. They are often
inconsistent and difficult to
correct.
b) Accuracy is contained in the tools. It depends on the quality of the tools.
Inaccuracy
means error. Errors are often
systematic and can therefore be detected and
corrected.
