Chi Square Tests for the Difference between Correlated Weighted Kappas and Correlated Unweighted Kappas

Large sample chi square tests of the significance of the difference between two correlated kappas, which may be weighted or unweighted, are derived. Two cases are presented: one judge in common between the two kappas and no judge in common. An illustrative calculation is included.
