Measurement Uncertainty Budgets
This workshop presents a combination of lecture and classroom exercises to demonstrate the principles of measurement uncertainty analysis.
Course Delivery: In-Person Training, Online Self-Paced, Training for Teams

Training for Teams
In-Person Training
In-Person Training consists of public classes conducted by one of our subject matter experts at one of our designated locations in one or more consecutive days.
Target Audience
Calibration technicians, quality managers, engineers, quality technicians, and other users of uncertainty budgets.
Prerequisites
Students must bring a scientific calculator, such as the TI30Xa, to each class. Students must also supply their own laptop with permission to install free software.
Course Objectives
All measurements are subject to uncertainty and a measured value is only complete if it is accompanied by a statement of the associated uncertainty. This class will help you calculate the probability of the uncertainty and ensure your measurement system is compliant with ISO 17025. Covered in the training will be basic terminology, basic statistical concepts, computations and correlations, as well as how to analyze and interpret data. Within this class we will also review the ISO Guide to the Expression of Uncertainty in Measurement (GUM).
Agenda
DAY 1
- Basic Terminology
- Why do we need uncertainty and what is it?
- Importance of uncertainty in measurements
- Uncertainty analysis concepts
- Measurements, error and uncertainty
- Uncertainty components (contributors to error)
- Random and systematic errors
- Basic Statistics Concepts
- Populations and Samples
- Data, means, modes and medians
- Standard deviation and variance

- Combining uncertainties (Applying RSS)
- Correlated and uncorrelated data
- Sensitivity coefficients (multipliers for weighting)
- Degrees of freedom
- Expanded uncertainty
- Understanding the Uncertainty Budget
- Role in accreditation, liability, traceability
- Accepted definitions of uncertainty, e.g., GUM (others?)
- Analyzing and interpreting data
- Uncertainty statements and notes
DAY 2
- Controlling Measurements and Processes
- Measurement assurance programs
- Check standards
