Statistical methods of uncertainty evaluation. Guidance on evaluation of uncertainty using two-factor crossed designs1 Scope This Technical Specification describes the estimation of uncertainties on the mean value in experiments conducted as crossed designs, and the use of variances extracted from such experiments and applied to the results of other measurements (for example, single observations). This Technical Specification covers balanced two factor designs with any number of levels. The basic designs covered include the two way design without replication and the
