Abstract

Studies in applied behavior analysis have used percentage agreement as an index of interobserver reliability. Because percentage agreement is inflated by chance agreements, kappa has been recommended as a preferred alternative. In this article, we present a procedure to estimate maximum and minimum kappa from percentage agreement with limited information. The procedure will facilitate comparisons between studies and the reassessment of the reliabilities of previous studies.
