| Popis: | The authors presumed that it was possible to replace certain criteria of the expert system aimed at evaluating actual quality of basketball players, proposed by Trninić, Perica and Dizdar (1999), with the corresponding indicators of situation-related efficiency (official statistics of the game). Hence, the aim of this study is to verify the potential of establishing such a combined model of expert system that would consist of both the evaluation criteria and certain number of objectively measurable aspects of actual quality (player's partial performance or playing efficiency) and to determine its pragmatic validity. To achieve the aim the sample comprised of 60 basketball players that were competing in the Croatian First Division League in the 1998/99 season was tested. The sample and their quality of play was described by the two sets of different types of data: 1) the 13 situation-related efficiency data, that is official FIBA statistics of the game, utilised to objectively assess performance or playing effectiveness of players, were collected at 132 games played by 12 teams, and 2) the evaluation data, subjectively assessing actual quality of players, that is their perceived overall performance, were collected at the end of the season from the10 basketball trainers (experts) who coached the above- mentioned teams in the same season. On the basis of relatively high correlations within the 7 pairs of mutually equivalent variables (from 0.63 to 0.84) and the extremely high correlation (0.97) obtained beetween the perceived overall performance (actual quality), subjectively assessed with respect to the 19 criteria of the original expert evaluation system, and the overall performance (actual quality) assessed by the combined model (where the 8 evaluation criteria had been replaced by the 7 corresponding indicators of playing efficiency), it is feasible to consider the combined model of expert system as an acceptable tool for more objective and economical assessment of actual quality of basketball players. |
