Recent Developments in Reliability Analysis.
Krippendorff, Klaus
When one wants to set data reliability standards for a class of scientific inquiries or when one needs to compare and select among many different kinds of data with reliabilities that are crucial to a particular research undertaking, then one needs a single reliability coefficient that is adaptable to all or most situations. Work toward this goal from 1967 through the present is discussed. The agreement coefficient alpha has been defined as zero when the observed disagreement equals the disagreement that would be expected under conditions of chance, one when observed disagreement is absent, and negative when the observed exceeds the expected disagreement. A more recent definition corrects for small sample sizes, as an equation demonstrates. The route by which the equation was derived is traced to show generalization to: (1) any metric; (2) "m" observations or instruments; (3) missing data; (4) multiple values; and (5) many variables. Computer implementation and testing are planned to refine this versatile analytical device for reliability analysis in content analysis, survey research, and other data-generating procedures. (SLD)
