基于RSR统计分析世界杯女排攻防综合能力

Based on RSR Statistical Analysis of the World Cup Women's Volleyball Team Attack and Defensive Ability

利用秩和比法（RSR）对2015年女排世界杯的攻防能力进行等级评价，并将中国队与美国、日本等强国的攻防技术对比分析。研究表明：进攻方面中国、塞尔维亚、美国、俄罗斯和日本的RSR值处于B级水平，韩国处于C级，多米尼加处于D级；防守方面中国、塞尔维亚、美国、俄罗斯的RSR介于0．60～0．79之间；攻防综合上中国和美国的RSR值分别是0．90、0．95处在A级评价标准行列。在攻、防、攻防上RSR排名与世界杯最终排名呈显著性相关。中国队在与美国等四个国家的攻防技术上表现在进攻方面除在发球得分和传球失误方面，其余进攻指标均低于五强，发球得分与失误与其余四国相比呈显著性差异（P〈0．05）；在防守方面拦网和接发球防守均好于其余四国，拦网得分指标、防守救球与其他四个国家呈显著性差异（P〈0．05）。

By using the method of Rank-sum ratio （RSR）, to evaluate and analysis about offensive and defensive ability between China, America, Japan and other countries in the 2015 Women＇s Volleyball World Cup. The results showed that ： in the attack, China, Serbia, America, Russia and Japan＇ s RSR is at the B level, Korea at the C lev- el, Dominican at the D level; In defense, China, Serbia, America and Russia＇ s RSR ranging from 0.60 to 0.79 ; In defensive and offensive ability of China and America RSR is ranging from 0.90 to 0.95. In the attack, defense, of- fensive and defensive, the correlation coefficient between world cup ranks and RSR value was significantly associat- ed. In the serves and setting fault, China is better than the other four countries, the rest of spike, block and so on. It is lower than that, while the serves and setting fault was a significant difference （ P 〈 0. 05 ）. On defense defensive block and reception serves are better than the rest of the four countries, while block and dig score index are signifi- cant differences （ P 〈 0.05 ）.
