5533: Basic Uncertainty Concepts

This 2 hour webinar provides a very basic introduction to uncertainty calculations and reporting using the 8-step process published in NIST SOP 29 (NISTIR 6969), beginning with some definitions and concepts from the Guide to the Expression of Uncertainty in Measurement (GUM) with simple calculations. NOTE: The content is similar to what is covered in the Fundamentals of Metrology seminar and is a useful pre-cursor or review for content covered during the course and will include calculations and a short application quiz. The session will end with an optional 30 minute session for Questions and Answers.

Learning Objectives:

At the end of this session, using SOP 29 and course notes, participants will be able to:

• DEFINE: standard uncertainty, expanded uncertainty, coverage factor, Type A methods, Type B methods;
• DESCRIBE the importance of knowing and evaluating measurement uncertainty; ;
• Be able to: SPECIFY, IDENTIFY, QUANTIFY, CONVERT, COMBINE, EXPAND, EVALUATE, and REPORT uncertainties for a simple scenario;
• EXPLAIN the concepts of uncertainty and its relationship to metrological traceability;
• IDENTIFY documentation requirements for uncertainty calculations within a calibration laboratory; and
• IMPLEMENT an uncertainty budget based on concepts presented in NISTIR 6969, SOP 29 and the Guide to the Expression of Uncertainty in Measurement.
