# Analysis and Parameterization of Sports Performance: A Case Study of Soccer
## 4 Dataset and Parameterization
Table 10 shows a comparison between the result offered by the ES and the real ranking of the season where this work has been applied so that it is able to distinguish the best and worst team of the 2021-2022 LaLiga Santander season, Real Madrid CF, and Deportivo Alaves. In addition, the ranking of the ES agrees 75% with reality if the top four ranked teams and from 5 th to 12 th positions are considered. Finally, the ranking of the ES agrees 87.5% with reality if the last eight teams of the championship (from 13 th to 20 th) are taken into account, and the results obtained in the analysis of these data have been satisfactory and promising. It would be necessary to apply it to other data sets and on other types of sports so that its capacity to make these predictions could be adjusted. Considering the results obtained, we can state that the performance of a team cannot be calculated as the sum of the individual skills of the players because there are other determining factors that need to be taken into account. The relationship among team members, as well as their ability to work together in a match, are crucial aspects that are not being valued in the ES, and therefore, this would give us an idea not of the collective performance of the team but of the individual performance, i.e., the potential of these players. While it is true that the performance of the ES is promising in terms of the predictions made, it is necessary to continue working on adding these factors, in addition to the coach's strategy and tactics, as they are fundamental elements that can significantly influence the team's performance. \begin{table}
