This report, the third in a series evaluating various methods for determining the effectiveness of display formats, contains the description, development, and testing of a checklist instrument on four formatted displays. This work supports the United States Nuclear Regulatory Commission's effort to develop valid and reliable techniques for the evaluation of computer generated displays currently being implemented in nuclear power plant control rooms. Certified Operators at a DOE Research Reactor used the checklist to evaluate four formats - BARS, STARS, METERS, and pressure temperature map (P-T map). A weighting scheme was developed using nine judges and an equal appearing interval technique. Four empirical factors were identified: display characteristics, information content, information format, and information quality. Tests of significance were run between display formats for BAR, STAR, and METER, as well as data collected in a second experiment between the display formats BAR and P-T map. Validity and reliability coefficients were calculated and presented. The results demonstrate the checklist to be a reliable and valid instrument for a display evaluation effort.
