Mutual exclusiveness refers to the concept that every observation can only be classified in terms of one and only one attribute, with no overlap or ambiguity. Reliability refers to the consistency and stability of research results, validity refers to the accuracy and relevance of research findings, and exhaustiveness refers to the completeness and comprehensiveness of a classification system. While these concepts are all important in research, mutual exclusiveness is the most closely related to the idea of classifying observations without ambiguity or overlap.
