1 Two students are doing an experiment to investigate reaction times. The diagram shows their
experiment.
Tester
0.0 cm
Participant
(a) The statements outline the method used. They are not in the correct order.
A The tester lets go of the ruler.
B The participant catches the ruler as soon as they realise the tester has let go of the
ruler.
C The distance the ruler has dropped is measured.
D The participant has their fingers and thumb near, but not touching, the ruler.
E The tester holds a ruler above the participant’s hand.
(i) Write the letters in the boxes to show the correct order of the statements.
The first one has been done for you.

(ii) Suggest two improvements to the method that would ensure that the measurements
taken were valid.

(b) The experiment is repeated three times. Table 1.1 shows the results.

Distance ruler falls
Repeat
(cm)
1 8.4
2 7.9
3 7.7
The students conduct a fourth repeat. The distance recorded is 12.7 cm.
Suggest one reason why this value of 12.7 cm is greater than the first three repeats.

.............................................................................................................................................. [1]
(c) The students find some data they can use to convert the distance fallen by the ruler into a
reaction time. This information is in Table 1.2.

A second participant repeats the experiment. The mean distance the ruler falls is 6.7 cm.
Use Table 1.2 to estimate their reaction time.
