Introduction to Measurement Uncertainty

Learn how measurement uncertainty (MU) is used in laboratories to ensure reliable and accurate measurement results.

Overview

This introductory course provides an overview of key concepts in measurement uncertainty. It covers the fundamental principles of measurement, how to identify common sources of uncertainty and outlines the steps for quantifying and reporting uncertainty according to international Standards.

Outcomes

Define key concepts in measurement uncertainty.
Explain the significance of measurement uncertainty in laboratory work.
Describe measurement uncertainty requirements in international Standards such as ISO/IEC 17025.
Distinguish between random and systematic errors and their impact on measurement results.
Apply statistical methods to analyse measurement data including calculating mean, standard deviation and confidence intervals.
Identify and quantify the sources of uncertainty in a measurement process using appropriate techniques and tools.
Determine combined uncertainty and communicate this value effectively in reports and technical documents.

Audience

This course is ideal for laboratory professionals and technical staff involved in measurement processes and/or quality assurance. It is particularly valuable for:

Laboratory technicians and scientists – who perform measurements and need to understand how uncertainty in their measurements can impact the reliability of results
Quality managers – responsible for ensuring the reliability and accuracy of laboratory outputs and maintaining compliance with quality standards
Laboratory managers and supervisors – who oversee measurement processes and need to make informed decisions based on measurement data
Calibration technicians – who need to understand and apply uncertainty concepts in their calibration work
Researchers – who need to accurately report measurement results and their associated uncertainties
New Graduates – entering laboratory roles and seeking to gain insight into measurement practices
Professionals from industries relying on precise measurements – such as manufacturing, environmental monitoring and healthcare.

This course is also beneficial for laboratories preparing for or maintaining accreditation to Standards like ISO/IEC 17025, where demonstrating competence in evaluating MU is a requirement.
