普通高校篮球选项班“两轮择优”罚篮考试方法研究

为了探讨合理的篮球罚篮期末考试方法,运用数理统计法对广东药科大学篮球选项班586名男生的两轮罚篮考试成绩进行比较研究。结果发现:两轮罚篮结果的命中个数分布有差异(秩和检验结果:Z=24.410,P<0.001),整体而言,在第二轮罚篮考试中,命中个数更多;配对t检验结果验证了学生们两轮罚篮考试的结果有差别(t=12.804,P<0.001),从个体上而言,第二轮结果普遍优于第一轮;配对卡方检验结果提示两轮罚篮成绩有关联(χ2=147.800,P<0.001)。因此,在排除第一轮考试发挥不稳定的因素后,经过两轮考试基本可以反映出学生的真实水平。建议普通大学生篮球罚篮期末考试采用2轮测试,以绩优成绩为准的办法进行。

Comparative Research on the Results of Two Rounds of Penalty Shot of University Students

In order to explore the reasonable examination method of penalty shot,we use mathematical statistics and theory analysis to compare the results of the two rounds of penalty shots of 586 students of Guangdong pharmaceutical university.We found that the results are different.On the whole,the goals of the second round are more than the first round which has been proved by t test.In the individual,the second result is mostly better than the first result.The two results are relevant byχ2 test.Therefore,two round tests can mainly reflect the real shooting level of students without thinking the instability of the first shooting.It is suggested that two rounds of tests should be adopted in the final examination of basketball penalty shot for ordinary college students,and the results should be taken as the criterion.
