REXALL is a flexible program within the CODAP (Comprehensive Occupational Data Analysis Programs) system designed primarily for analyzing judges' task-factor ratings, and may be used for identifying divergent raters. Divergent raters are those whose ratings are significantly different from the other raters' ratings. They may be the noncooperative raters who simply generate an arbitrary pattern of responses rather than try to follow the instructions, or they may invert the rating scale, or they may actually perceive the tasks differently. This report uses data from an actual study to show how REXALL is used to detect divergent raters, and to decide whether or not to delete them from the study since they may invalidate task means computed from ratings. It then uses the raw data from the study to verify the validity of the decisions made on the basis of the REXALL output. (Editor/WL)
