A Moid of Performance Measures in Baseball

The study was concerned with empirically confirming the proposed classification of the performance measures in baseball into tertiary, secondary, and primary measures based on their proximity to skill execution and task performance and with the extent to which these measures were contaminated by external factors. The data consisted of various performance measures derived from the box scores of games played by 10 teams from the National Collegiate Athletic Association during the 1988 season ( N =381 games). For confirmatory purposes» the total sample was subdivided into home and away samples ( N=762 observations). The results of correlational and regression analyses supported the proposition that the secondary measures would be more closely related to the tertiary measures than would the primary measures. Further» ran differential was the superior tertiary measure relative to win/loss and ratio of final score in reflecting skill execution and task performance. Practical applications of the model and directions for future research are then discussed.
