Particularly, the present study is focused on the performance evaluation in football using univariate and multivariate methods. The univariate approach is given by Z-CELAFISCS methodology, which was developed with the purpose of identifying talents in the sport. The multivariate approaches are given by the construction of indicators, speci cally by means of principal component analysis, factor analysis and copulas. These indicators allows the reduction of the dimensionality of the data in studying, providing better interpretation of the results and improving comparability between the performance and assortment of individuals. To facilitate the use of the methodology studied here was built an online statistical system called i-Sports. / principal objetivo do trabalho é apresentar ferramentas estatísticas que permitam a comparação de indivíduos em uma determinada modalidade esportiva. Particularmente, o estudo exposto é voltado à avaliação de desempenho em futebol, utilizando métodos univariados e multivariados. A abordagem univariada é dada pela metodologia Z-CELAFISCS, desenvolvida com o propósito de identi car talentos no esporte. As abordagens multivariadas são dadas pela construção de indicadores, mais especi camente por meio da análise de componentes principais, análise fatorial e cópulas. A obtenção desses indicadores possibilita a redução da dimensionalidade do estudo, fornecendo melhor interpretação dos resultados e melhor comparabilidade entre o desempenho e rankeamento dos indivíduos. Para facilitar a utilização da metodologia aqui estudada foi construído um sistema estat ístico online chamado de i-Sports.
