Determining the degree of inconsistency in a set of paired comparisons

Consistency in paired comparison data is defined. Two types of inconsistency which may arise are defined. Computational formulas for these types of inconsistency are derived, and examples illustrating the use of these formulas are presented.These ideas were developed while the first author was on the staff of the Research Center for Human Relations. The work was made possible by the ONR contract NONR 285(10). The authors are indebted to Jack Moshman for his helpful critical suggestions.
