Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.
Explanation:
Precision is the ability to reproduce the same set of result from a measurement. The more repeatability a measurement is, the more precise it is.
From the given pool of data, it is easy to determine which set of data is more precise over the other.
Thomas measurements: 10.0 A, 11 A, and 8 A
Nikola measurements: 9.0 A, 9.2 A, 8.8 A
Using the range method, it is possible to find the precision in this pool of data.
Method and Solution:
Find the range of the sample:
Range = highest value - lowest value
Thomas measurement; Range = (11-8)A = 3.0A
Nikola measurement; Range = (9.2-8.8)A = 0.4A
Find the mean of the samples:
Mean of Thomas measurement = =
= 9.7A
Mean of Nikola measurement = =
= 9A
Now let us quote the range of value of the mean of each measurement:
Thomas 9.7±3.0A
Nikola 9.0± 0.4A
Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.
