  This note presents a combination of published and preliminary electroweak
results from the four LEP collaborations and the SLD collaboration which were
prepared for the 2002 summer conferences. Averages from Z resonance results are
derived for hadronic and leptonic cross sections, the leptonic forward-backward
asymmetries, the tau polarisation asymmetries, the b-bbar and c-cbar partial
widths and forward-backward asymmetries and the q-qbar charge asymmetry. Above
the Z resonance, averages are derived for di-fermion cross sections and
forward-backward asymmetries, photon-pair, W-pair, Z-pair, single-W and
single-Z cross sections, electroweak gauge boson couplings, W mass and width
and W decay branching ratios. The main changes with respect to the experimental
results presented in summer 2001 are updates to the Z-pole heavy flavour
results from SLD and LEP, and new combinations of results above the Z pole. A
new investigation of the interference of photon and Z-boson exchange is
presented. For the first time, colour reconnection and Bose-Einstein
correlation analyses in W-pair production are combined.
  The results are compared with precise electroweak measurements from other
experiments, notably the recent final result on the electroweak mixing angle
determined in neutrino-nucleon scattering by the NuTeV collaboration. The
parameters of the Standard Model are evaluated, first using the combined LEP
electroweak measurements, and then using the full set of electroweak results.
