Objective: Multivariate statistical analysis viz. Cluster Analysis (CA) was performed to validate the experimental findings. Methods/Statistical Analysis: The (In0.955CO0.045)2O3 samples were concocted by the typical solid state reaction route. The resulting materials were pelletized and sintered in hydrogen atmosphere. Subsequently, hydrogenated pallets were dehydrogenated by further heating for 7h in air. The samples were thoroughly characterized using X-ray diffraction. FULLPROF Program is used to refine the crystalline structures. Magnetic hysteresis loops were evaluated using Vibrating Sample Magnetometer (VSM) at room temperature. Hierarchical CA was accomplished on the normalized data set (samples) by means of the Ward's method, using Euclidean distances as a measure of similarity. Findings: The X-Ray Diffraction (XRD) study confirmed the formation of cubic bixbyite structure for In2O3, In0.955CO0.045)2O3 and In0.955CO0.045)2O3:H samples. The magnetic study at Room Temperature (RT) confirms that pure In2O3
