Combined analysis of precision electroweak results

Preliminary and published results on measurements of parameters of the electroweak standard model are presented. Averages are derived from measurements of cross sections and asymmetries measured by SLD and the four LEP experiments, of the electroweak mixing angle measured in neutrino-nucleon reactions, of the W mass measured at LEP-2 and at the TEVATRON, and of the mass of the top quark measured by the TEVATRON experiments. These data are used to test the standard model and to constrain its parameters. (33 refs).
