Physics (AS & A Level) · Oct / Nov 2023 · Paper 13 · Question 3

A set of repeated measurements is made of a fixed quantity. An average of these measurements is calculated. What is the effect of averaging on the random error and the systematic error in the measurements?

1. ARandom error and systematic error are both reduced.
2. BRandom error and systematic error are both unaffected.
3. CRandom error is reduced but systematic error is unaffected.
4. DRandom error is unaffected but systematic error is reduced.
