5630: 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) and includes some 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 includes calculations and an integrated application quiz. The session ends 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.

Materials & Supplies:

None.

Prerequisite(s):

There are no prerequisites for this webinar. Knowledge of basic mathematics and statistics is expected and must be used for successful completion.

Pre-Work:

Read NISTIR 6969, SOP 29 (https://www.nist.gov/pml/weights-and-measures/laboratory-metrology/stan…)

Post-Work:

Submit Student Notes (Highlights, Applications, and Application Quiz).

Minimum Requirement(s):

Successful Completion includes completing pre- and post-work assignments, full attendance and participation in the session activities and discussion, including the integrated quiz/calculations.

Audience:

Laboratory metrology staff and administrators who are new to uncertainty calculations or who would like to review the 8-step process of SOP 29.  The session would also be useful for metrology staff who will be conducting on-the-job-training for new staff members.

Cost:

The current fee for webinars is $249 and confirmed participants will be provided payment instructions.  Registration fee payment is due by February 24, 2020.  Registration fees for State weights and measures metrologists are funded by NIST OWM.
