Adjustments for Rater Effects in Performance Assessment.

Houston, Walter M.; And Others

Applied Psychological Measurement, v15 n4 p409-21 Dec 1991

The effectiveness of alternative procedures to correct for rater leniency/stringency effects was studied when true scores were known. Ordinary least squares, weighted least squares, and imputation of the missing data consistently outperformed averaging the observed ratings; and the imputation technique was superior to the least squares methods.
