Uncertainty Sidekick is a free application for calculating and analyzing measurement uncertainty that incorporates the concepts and methods presented in the International Organization for Standardization (ISO), Guide to the Expression of Uncertainty in Measurement (GUM). Uncertainty Sidekick also contains state-of-the-art analysis methods and techniques designed to guide you through the process of developing uncertainty estimates for direct measurement scenarios. Direct measurements basically consist of a measuring parameter "Y" that directly measures the value of subject parameter "X." That is, the value of the subject parameter is obtained directly by measurement and is not determined indirectly by computing its value from other measured quantities or variables.
Uncertainty Sidekick incorporates specially designed screens and worksheets that help you identify sources of error common to most direct measurement processes and estimate the uncertainties in these errors. It includes notes pages for all uncertainty analysis worksheets and screens to store pertinent information and provides the capability to preview and print analysis reports in various levels of detail. It also comes with a comprehensive Help function and 70+ page User Manual with a chapter that covers the basic statistical methods and concepts that are key to understanding measurement uncertainty analysis.
