Module 1.1: Precision and Accuracy

 


The vertical precision was 5.75m, while the vertical accuracy was 5.92m. This means that the points were more precise in their elevation than they were accurate. The inverse was true for horizontal precision and accuracy, where the estimated horizontal precision was 4.28m, while the accuracy is 3.48m.This means that a large percentage of the measurements taken were within 4.28m of the average, meaning there was less precision than accuracy in these points, as the average of all points was 3.48m away from the correct point. Accuracy and precision are necessary when conducting repeatable experiments, and points that are not within a certain distance of one another can create a lack of repeatability in an experiment, even if the average of these points is accurate.This means that there was a bias for horizontal accuracy, as it seems the points were significantly incorrect in the vertical measurement on average over the horizontal measurement.
