The basketball evaluation system (A computerized factor weighted model with measures of validity)

Sažetak
In the United States, coaches at all levels of play have devised player evaluation systems. As early as 1941, Foster “Phog” Allen, the coach who replaced James Naismith at the University of Kansas, developed a value weighted factor rating system to determine the effectiveness of offensive and defensive performance (Elbell and Allen, 1941). This system and all others to date have posed a number of problems. They are either too cumbersome to administer, are based on subjective and/or outdated criteria, and/or do not distinguish between positions of play (Swalgin, 1987). The author wishes to propose a more scientific approach to player evaluation. The aim of this research was to enhance the Basketball Evaluation System (BES), a computerized performance evaluation model which grades player performance in relationship to “position of play’ and “time played” under game conditions. Weighting factors for an established set of performance criteria were developed from a survey of expert coaches. The weighting factors were then incorporated into the original model in an attempt to strengthen the validity of scores produced for overall performance. Scores for the unweighted and weighted models were then correlated with a set of criterion scores established from another group of expert coaches. The results indicate that both models correlated highly with the coaches’ criterion scores. For the unweighted model, r = .757 and for the weighted model, r = .798. The difference between the correlations was not. statistically significant. The addition of factor weighting did however add to the face validity of the model, giving coaches a quantitative tool to measure individual performance in relationship to “position of play” and “time played”.
