Key comparisons are carried out by the Consultative Committees (CCs) of the Comite International des Poids et Mesures (International Committee for Weights and Measures, CIPM) as required in the mutual recognition arrangement (MRA). Three methods for determination of the key comparison reference value (KCRV) of inconsistent comparison data are proposed in this study. These methods are respectively based on the premise of (1) unknown biases of individual measurement values, (2) underestimated uncertainties of individual participants, or (3) additional and common uncertainty. Bayesian statistics were employed for the analysis using locally uniform priors. In the case of the first premise, Procedure B in the CIPM guideline (Metrologia 39, 589-95 (2002)) can be derived in the Bayesian context. In the case of the second and the third premises, the weighted mean is a possible candidate for the KCRV. These methods are exemplified using the key comparison data.
