b. Because only a finite num ber of m easurem ents can be m ade, it is possible to determ ine only
an estim ate of random error.
Systematic error
Mean that would result from an infinite num ber of m easurem ents of the sam e m easurand carried out
under repeatability conditions m inus a true value of the m easurand.
Notes:
a.
System atic error is equal to error m inus random error.
b. Like true value, system atic error and its causes cannot be com pletely known.
Correction
Value added algebraically to the uncorrected result of a m easurem ent to com pensate for system atic
error.
Notes:
a.
The correction is equal to the negative of the estim ated system atic error.
b. Since the system atic error cannot be known perfectly, the com pensation cannot be com plete.
Correction factor
Num erical factor by which the uncorrected result of a m easurem ent is m ultiplied to com pensate for
system atic error.
Note:
a.
Since the system atic error cannot be known perfectly, the com pensation cannot be com plete.
