UNCERTAINTYLAB · PROFESSIONAL BROWSER TOOL

Put every uncertainty source into the same language first.

Build a Type A/B uncertainty budget, convert normal, rectangular, triangular, and U-shaped inputs to standard uncertainty, then apply sensitivity coefficients, correlation terms, and Welch–Satterthwaite effective degrees of freedom.

Effective degrees and expanded uncertainty

This is a first-order JCGM GUM budgeting aid. It cannot prove model completeness, distribution choice, identified correlation, or coverage probability. Nonlinear, strongly correlated, or non-Gaussian work may need Monte Carlo methods and metrology review.
