In this thesis we describe data quality considerations for the Side Muon Rang Detector (SMRD), one of the six sub-detectors of the ND280 near detector of the Tokai to Kamiokande (T2K) long baseline neutrino oscillation experiment. Herein we show that the data quality of the SMRD has taken good data 99.9584% of the time it has been recording data. Also, 99.676% of SMRD data channels are shown to be operating optimally. In addition we discuss the stability of the SMRD. We _x000C_find that based on a subset of data unbiased cosmic triggers have light yield of 112.8 +/- 0.3 p.e. vs. 100.7 +/- 0.5 p.e. for vertical and horizontal counters respectively. For a more stringent data set cosmic light yield for tracks with a nearly vertical path is determined to be 79:6 +/- 0.5 p.e. Detector stability is found to be related to the applied cosmic trigger mask, and this is evidenced in the increased stability of Run II over that of Run I. Also included is a basic introduction to neutrino physics and an overview of the T2K experiment.
