We report measurements of oscillation parameters from \ensuremathν_\ensuremathμ and \ensuremathν_\ensuremathμ disappearance using beam and atmospheric data from MINOS. The data comprise exposures of 10.71\ifmmode×\else\texttimes\fi1020 protons on target in the \ensuremathν_\ensuremathμ-dominated beam, 3.36\ifmmode×\else\texttimes\fi1020 protons on target in the \ensuremathν_\ensuremathμ-enhanced beam, and 37.88 kton yr of atmospheric neutrinos. Assuming identical \ensuremathν and \ensuremathν oscillation parameters, we measure |\ensuremathΔm2|=(2.41_\ensuremath-0.10+0.09)\ifmmode×\else\texttimes\fi10^\ensuremath-3 eV2 and sin2(2\ensuremathθ)=0.950_\ensuremath-0.036+0.035. Allowing independent \ensuremathν and \ensuremathν oscillations, we measure antineutrino parameters of |\ensuremathΔm2|=(2.50_\ensuremath-0.25+0.23)\ifmmode×\else\texttimes\fi10^\ensuremath-3 eV2 and sin2(2\ensuremathθ)=0.97_\ensuremath-0.08+0.03, with minimal change to the neutrino parameters.
