(a)[2]
For each item below, tick one box to show whether the experimental technique would reduce random error, systematic error or neither. The first row has already been done as an example.
(b)
A certain time interval is measured repeatedly many times, and the readings are not all the same. The outcomes are shown in Fig. 1.1. The true value of the time interval is $10.1\,\text{s}$.
(b(i).1)[1]
State how the readings on Fig. 1.1 demonstrate the existence of a systematic error.
(b(i).2)[1]
State how the readings on Fig. 1.1 demonstrate the presence of a random error.
(b(ii).1)[1]
State the expected changes to Fig. 1.1 for experimental measurements that are more accurate.
(b(ii).2)[1]
State the expected changes to Fig. 1.1 for experimental measurements that are more precise.
