The Tokai-to-Kamioka (T2K) experiment is a long-baseline neutrino-oscillation experiment that searches for neutrino oscillations with measurements of an off-axis, high purity, muon neutrino beam. The neutrinos are detected 295 km from production by the Super Kamiokande detector. A near detector 280 m from the production target measures the unoscillated beam. This thesis outlines an analysis using samples in the near detector and Super Kamiokande to measure the disappearance of muon neutrinos. To manage the complexity this analysis, a Markov Chain Monte Carlo framework was used to maximize a likelihood to estimate the oscillation parameters. T2K Run 1+2+3 data (3.010 x10²⁰ POT) is used for the analysis. The estimates for the oscillation parameters are:
( sin² (2θ₂₃ ), Δ m²₃₂ ) = (0.999,2.45 x10ˉ³ [eV²]),
and the 90% 1D bayesian credible intervals:
0.9340 < sin² (2θ₂₃ ) < 1.000
2.22 x10ˉ³ < Δm²₃₂ [eV²] < 2.74 x 10ˉ³ / Graduate / 0798
