Error, Noise, Precision, and Accuracy

In this lab, students explore the concept of error and its sources. They will measure and calculate the precision and accuracy of a simulated measurement and multiple instruments. Finally, they observe noise on a measurement signal and a method of mitigating that noise through filtering. These concepts combine to indicate that there’s a difference between a measured value and its true value. By quantifying and expressing things like precision and accuracy, we can identify the performance of our system and compare it with the tolerances that our solution requires.
