Results/Comparison to Theory / Answers
The caliper and the micrometer were checked for the calibration. The results showed zero offset before and after experiment. Since there are differences in the measured data; the calculation of density varies. There are 3 variables that we have to take into account for calculating the density of the copper rod. The length plays the largest role in the uncertainty of the copper rods density since it has the largest deviation. The Vernier calipers were the most accurate because it showed the smallest deviation. Our experiment carried out exactly how the theory explained it would. We measured the same part a multitude of times and received varying data. Calculating the density from the averaged data made the value more accurate, and when combined with the standard deviation; our values for density became that much more accurate.
