Techniques and methods for computing, estimating, or placing bounds on the errors of expressions (formulas) based on knowledge of error distributions, error intervals or bounds of variables and parameters entering those expressions, and of methods used in the computations.

Measurements and uncertainties

All measurements in physics have some uncertainty attached to them. The uncertainty is a measure of how well a scientist knows the "true" value of the measured quantity.

Propagation of uncertainties

Least-squares fitting

Common statistical distributions in physics

Poisson distribution

Gaussian (normal) distribution
