Introduction to Measurement Uncertainty (EMU 101)

This course is a suitable introduction for both calibration and testing laboratory participants, focusing on the concepts and mathematics of the measurement uncertainty evaluation process. The participant will gain an understanding of the statistical techniques required to estimate measurement uncertainty, and will practice those skills to create basic uncertainty budgets.

 

Course Content

  •  Introduction:
    • The requirement for uncertainty estimates.
    • Uncertainty References, Definitions, The GUM; and other more user-friendly material.
  •     Mathematics:
    • Significant digits, scientific notation, and units conversion.
    • Basic statistics used in the GUM.
  •     Estimating Uncertainties:
    • Type A and Type B methods.
    • Distributions, confidence levels, standard deviation.
    • Distributions and Applying corrections.
    • Outside limit estimates.
    • How many measurements (sample size).
    • Combination of uncertainties.
    • Correlated vs. uncorrelated.
    • Expanded uncertainty; and confidence intervals.

Prerequisites

Participants should be:
- familiar with statistical functions in spreadsheets, and
- able to apply basic measurement uncertainty evaluation/estimation principles (Introduction to Measurement Uncertainty EMU 101)

 

EQUIPMENT NEEDED:

The participant will need to bring a laptop computer with Microsoft Excel or similar spreadsheet installed.

 

Target Attendees

This course is designed for personnel working in calibration, metrology, testing or other measurement fields.

PLEASE NOTE: This class is suitable for those laboratories whose tests and/or calibrations fall within the category of Type IV or V in accordance with A2LA's P103 - Policy on Estimating Measurement Uncertainty for Testing Laboratories.

Learning Outcomes

After successful completion of the course, the participant will be able to:  

1. Apply tools and techniques learned during the course to their measurement processes;
2. Employ the statistical capability of spreadsheet applications;
3. Identify and Utilize supplemental tools for determining Type A measurement uncertainty (Repeatability and Reproducibility); and
4. Demonstrate techniques for calibration interval analysis and other improvements to the measurement process.
