Distance Measurements Analysis
Ten teams of students measured the perimeter of a seven-sided traverse using pacing and taping. Each leg was measured twice. The standard deviations of the measurements of the perimeter showed that pacing gave much more variable results. Pacing also had a much wider certainty range at different probabilities.
As can be seen in the table above the range of measurements is much greater. This is somewhat expected as it is the combined results of ten different groups. Also, greater practice would result in less variability in the measurements.
The chart shows the standard deviations for the measurements of each leg and illustrates the difference in the results.
