Practice question · True or false
Averaging repeated measurements reduces random error but not systematic error.
Hints
- What does a systematic error do to every reading?
- It shifts them all the same way, so averaging preserves it.
Show the answer
True
Why
True, random scatter averages toward zero, but a systematic offset shifts every reading identically and survives averaging untouched. Only calibration removes it, which is why the thermocouple exercise exists.
