第18届世界杯足球赛红黄牌特征的分析

An analysis on the characteristics of red and yellow cards showing in the 18^(th) FIFA World Cup

运用文献资料法、观察法、数理统计法等,对第18届世界杯足球赛裁判员出示红黄牌情况进行整理分析,结果显示:下半场的最后一个时间段出现黄牌数最多;第一张黄牌集中出现在上半场的中段;下半场的红牌数高于上半场;出示红黄牌的原因比较集中。

We analyzed the condition of red and yellow cards showed by the referees in the 18th FIFA World Cup by document, abservation, and math analysis. The results show that most yellow cards are showed in the last part of second half; the first yellow cards come up in the middle of the first half; and that the number of red cards showed in second half is more than in the first half; and the reasons why red and yellow cards are showed are mostly same.
