    Overview

    Whenever a measurement is made there will be some uncertainty about the result. Knowledge of the uncertainty allows a judgement to be made on whether the data are likely to be fit for purpose.

    If comparisons of results are being made, a meaningful interpretation can only be achieved if the uncertainty is known. This course provides a practical approach to evaluating uncertainty in testing laboratories.

    Programme Content and Key Areas

    The course will cover:

    Day 1 – The principles

    • Introduction to the concept of measurement uncertainty
    • Statistics for measurement uncertainty estimation
    • The basic principles of evaluating uncertainty
    • Converting data and combining uncertainties
    • Quantifying uncertainty components
    • Evaluation of an uncertainty budget using spreadsheets
    • How to handle precision.


    Day 2 – The practice

    • Using data from validation studies
    • Cause and effect analysis
    • Dealing with data from recovery estimations
    • Using precision data from validation studies
    • Handling uncertainty for large concentration ranges
    • Using and conveying uncertainty estimates.
