Abstract
This paper aims to analyze the statistical parameters and to determine the differences between the water polo tournament in Sisak and the water polo tournament in Sarajevo. Situational efficiency utilizing certain variables shows us the most important parts of the game during a water polo match. Statistics is a scientific discipline that studies the methods of collecting, collating, analyzing, and interpreting data. The sample consists of 336 water polo players, from six clubs of two age categories from the league of Canton Sarajevo and six clubs of two age categories from the Sisak International Tournament, in the "junior and cadet" categories for men born in 2003 and 2004, 2005. The sample of variables consists of 9 tests to assess situational efficiency in a water polo game that defines the main characteristics of a water polo match. The following will explain the observed variables: goals scored, attempt to score, goal from action, center to score, anchor to score, penalty, attempt from penalty defended by the goalkeeper or player missed, foul on the counter-attack, sprint - counter with a goal scored. The results of the H square test show that there are statistically significant differences (p .000) in the analyzed segments of the water polo match. It can be concluded that the teams in the tournament in Sisak are better organized because in every aspect they have achieved better results in comparison to the Sarajevo tournament. The teams from Sisak were better and faster swimming because a lot of goals were scored by counter-attack, more attempts to shoot at goal (Sisak), fewer penalties, which means that in Sarajevo is rough play and greater success of winning teams in penalties.
