This note presents constraints on Standard Model parameters using published and preliminary precision electroweak results measured at the electron-positron colliders LEP and SLC. The results are compared with precise electroweak measurements from other experiments, notably CDF and D at the Tevatron. Constraints on the input parameters of the Standard Model are derived from the combined set of results obtained in high-Q2 interactions, and used to predict results in low-Q2 experiments, such as atomic parity violation, Moller scattering, and neutrino-nucleon scattering. The main changes with respect to the experimental results presented in 2008 are new combinations of results on the W-boson mass and the mass of the top quark. Show Partial Abstract
