We have determined the electroweak parameters ${{sin}^{2}\ensuremath{\theta}}_{\mathrm{W}}$ and $\ensuremath{\rho}$ by a measurement of deep-inelastic neutrino-nucleon scattering used a fine-grained neutrino detector exposed to a narrowband neutrino beam at Fermilab. The sampling properties of our detector have permitted neutralcurrent and charged-current events to be well separated over a wide kinematic range, thereby allowing a determination of ${{sin}^{2}\ensuremath{\theta}}_{\mathrm{W}}$ and $\ensuremath{\rho}$ to be made with good statistics and small systematic errors. We have found ${{sin}^{2}\ensuremath{\theta}}_{\mathrm{W}}=0.246\ifmmode\pm\else\textpm\fi{}0.012\ifmmode\pm\else\textpm\fi{}0.013$ in a single-parameter fit.
