EffecTech Training AcademyStatistical methods and the measurement of uncertainty are important tools in the process of reporting gas measurement results and defined uncertainties are increasingly needed as part of contractual requirements. This 1-day course will provide students with the necessary understanding of the methods used to formulate basic uncertainty assessments for their particular requirements.

This course is for: those who want to know more about the commonly used statistical terminology and how statistics and other measurement parameters may be combined to formulate a robust uncertainty budget. The focus of the training will be on gas measurement and associated methods e.g. gas chromatography.

Course Content:

  • Introduction to the role of statistics in gas measurement
  • Random & systematic errors
  • Accuracy and precision
  • Errors in natural gas analysis / Calibration gas
  • Statistics of repeat measurements
  • Frequency distributions and the normal distribution
  • Confidence limits
  • Accuracy & traceability
  • Calibration / modelling calibration
  • Concepts of uncertainty
  • Compliance with limiting specifications
  • Evaluating & combining uncertainty
  • Use of Shewhart Quality Control (SQC) control charts

Students will examine the types of errors found in gas analysis and how they are propagated. The importance of repeat measurements, trend analysis and Monte Carlo simulations will also be covered. The course will include practical exercises to build confidence in developing spreadsheet-based uncertainty calculations.

Course requirements:

Attendees will need to bring a laptop with Microsoft Excel installed and have a basic understanding of how to use the program.

Course length: one day

All of EffecTech’s training courses can be provided in Uttoxeter, online, or at a customer site on request. For online delivery, the practical sessions are provided as demonstrations.
