We report measurements of oscillation parameters from \(\nu_{mu}\) and \(\bar{\nu}_{\mu}\) disappearance using beam and atmospheric data from MINOS. The data comprise exposures of \unit[\(10.71 \times 10^{20}\)]{protons on target (POT)} in the \(\nu_{\mu}\)-dominated beam, \(\unit[3.36\times10^{20}]{POT}}\) in the \(\bar{\nu}_{\mu}\)-enhanced beam, and 37.88 kton-years of atmospheric neutrinos. Assuming identical \(\nu\) and \(\bar{\nu}\) oscillation parameters, we measure \mbox{\(|\Delta m^2}| = \unit[2.41^{+0.09}_{-0.10}) \times 10^{-3}]{eV^{2}}\)} and \(\sin^{2}/!/left(2\theta \right) = 0.950^{+0.035}_{-0.036}\). Allowing independent \(\nu\) and \(\bar{\nu}\) oscillations, we measure antineutrino parameters of \(|\Delta \bar{m}^2| = \unit[(2.50 ^{+0.23}_{-0.25}) \times 10^{-3}]{eV^{2}}\) and \(\sin^{2}/!/left(2\bar{\theta} \right) = 0.97^{+0.03}_{-0.08}\), with minimal change to the neutrino parameters.
