The discriminant analysis method is one of the most important multivariate statistical methods used in processing descriptive data. It depends on building a function called (discriminant function), which is a linear combination of a group of independent variables that work to increase the difference between the average of the groups, and thus reduce the classification error. Therefore, the need has been demonstrated that the process of selecting young players for their positions in football in clubs in Karbala Governorate does not depend on modern methods, by taking the opinions of coaches, and also depends on personal experience and not on objective scientific foundations standardized in tests and measurements, and also depends on the opinion of the players to play in the positions they like, and tend to it even if it does not suit their specifications and capabilities, and this leads to not employing players correctly in the match.
Through the researcher’s follow-up and review of the youth league for Karbala football clubs, in addition to the researcher being a football practitioner, as well as the researcher’s review of literature and previous studies and personal interviews with experts and specialists, he noticed that there are differences in the selection of football players for their positions by coaches, which in turn leads to wasting time and effort with the players, without reaching the selection of the playmaker in football under 19 years old. The study aimed to identify the selection of playmaker players in terms of the effect sizes of skill performance and some bio-motor and visual abilities. The researcher used the descriptive approach (survey method), and the research community included club players in Karbala Governorate for the youth category, with a total of (190) players. The exploratory sample included (25) players, and the main experimental sample was (48) players. The fourth chapter included everything related to the results and their statistical processing to reach scientific results.
One of the most important conclusions reached by the researcher is that there are cases belonging to the group of playmakers who were incorrectly classified by the coaches, and it turned out that the correct classification for them is that they are non-playmakers, and that there are cases belonging to the group of non-playmakers who were incorrectly classified by the coaches, and it turned out that the correct classification for them is that they are playmakers. One of the most important recommendations reached is the need to focus on the variables (explosive ability, agility, speed endurance, visual reaction, visual tracking, peripheral vision), which have the largest impact and contribution in the classification of young playmakers, and the need to adopt the cur rent results as an indicator for the classification of playmakers.
