Unformatted text preview: EXPERIMENT 2. MEASUREMENT AND PRECISION
In the ﬁrst row in the example data table the calculated value of π is 3.17 ± 0.08 meaning,
within the experimental uncertainty a value as low as 3.09 or as high as 3.25 would be consistent with our measurement, therefore this example measurement agrees with the accepted
value of π . If the experimental uncertainty were not included however, the values would not
agree since 3.17 = 3.14. The calculated values for π in row 2 also agrees with theory, but
those in row 3 and 4 do not. Report
In addition to the standard elements of a well written lab report described in the introduction
to this manual, your report must include
1. An appropriate title
2. The objective of the lab
3. The general procedure for the experiment
4. Your groups data in an appropriate format
5. An example calculation of your uncertainty in π for one of the disks
6. A description of any systematic errors present in the experiment and a discussion of
how they were dealt with.
7. A summary of your results giving your average value for π along with an uncertainty
with and without any systematic errors corrected for.
8. A conclusion that states if you met the objective of the lab (i.e. did your measured
value agree with the accepted value for π ?) 17 ...
