Errors are an important part of a surveyor’s activities, because measurement is a basic element of all the professional activities that are undertaken by the profession. Sources and types of errors are discussed, as well as blunders, which are not errors. Means, residuals, standard deviation and histograms are covered. How to calculate standard deviation and how to use it to analyze measurement data and to measure accuracy rather than just precision are also presented.


By the end of each session, participants will be able to:
1. Understand why the ability to identify, compensate for and analyze errors is important to surveying
2. Learn about sources and types of errors
3. Know how to differentiate between accuracy and precision
4. Learn about residuals, means, histograms and standard deviation calculation
5. Learn to relate uncertainty in measurements and probability using standard deviation
