INTRODUCTION
The following experiment will investigate how uncertainty and cost can determine the type of measuring devices one might select when doing experiments. ... The uncertainty of each device used to find these two values effects what type of instrument is best for a given job. ... 754

Small Beaker 10. ... The values were to be expected, the more expensive the device the higher the resolution and consequently the lower the uncertainty associated with that device. ... The values in Table 4 are as expected, when the more expensive devices were paired together they produced the least uncertainty.
