Question

The reaction time, in seconds, of 12 people to a stimulant was recorded as follows:

2.6 3.6 3.1 4.6 2.7 3.3 2.8 4.7 3.1 2.4 4.5 1.9


Calculate the data range.

1.9


4.7


2.8


4.5

Answer 1

Data range = Maximum value - Minimum value
Data range = 4.7 - 1.9
Data range = 2.8

Therefore, the data range for the reaction time of the 12 people is 2.8 seconds.
