Practice question · Multiple choice
Averaging many measurements reduces random error but not systematic error. What makes the two kinds of error behave differently?
Hints
- Ask what happens if your balance reads 2 g heavy every single time.
- Precision and accuracy come apart here.
Show the answer
B. Random errors cancel on average; a systematic one does not
Why
A bias survives averaging untouched. This is exactly why calibration against a known standard is a separate procedure from repeating the measurement.
