Abstract:
This article explores the comprehensive strength of the attack and defense of the top 8 teams in the 18th Asian Cup through research methods such as mathematical statistics and non-integer rank sum ratio, and conducts equivalent evaluation and analysis of the attack and defense capabilities of the 8 teams. Research shows that the top 8 teams in this Asian Cup can be divided into three levels according to their offensive and defensive strength. The first level includes Qatar and Jordan, with a comprehensive WRSR value of 0.779 and 0.64 for offense and defense, respectively. The second level includes Japan, Iran, South Korea, Australia, and Uzbekistan, with a comprehensive WRSR value of 0.458, 0.507, 0.396, 0.590, and 0.478 for offense and defense, respectively. The third level includes Tajikistan, with a comprehensive WRSR value of 0.365 for offense and defense. The attack and defense WRSR values of each team are significantly correlated with their rankings (r=0.762), indicating that the WRSR value can truly reflect the attack and defense levels of the top 8 teams in this Asian Cup.
本研究运用数理统计、非整秩次秩和比等研究方法,探究第18届亚洲杯8强队伍的攻防综合实力,并对其攻防能力进行评价与分档。研究结果表明,本届亚洲杯8强队伍按攻防实力可分为3档:一档球队包括卡塔尔和约旦,其攻防综合WRSR值分别为0.779和0.64;二档球队包括日本、伊朗、韩国、澳大利亚和乌兹别克斯坦,其攻防综合WRSR值分别为0.458、0.507、0.396、0.590和0.478;三档球队为塔吉克斯坦,其攻防综合WRSR值为0.365。各队攻防WRSR值与排名之间存在显著性相关(r=0.762),表明该WRSR值能够较为真实地反映本届亚洲杯8强队伍地攻防水平。
