香港赛马会赛马成绩的差异性分析研究
|
摘要
搜集和整理香港赛马会2015年9月至2016年7月和2016年9月至2017年7月共2个赛季、9种赛程共计1551场赛马比赛的成绩.对两个赛季相同赛程赛马成绩的差异进行独立样本T检验,并对差异产生的原因进行分析.结果表明:两个赛季中1 000 m赛程和2 000 m赛程的比赛成绩无显著差异,1 200 m、1 400 m、1 600 m、1 650 m、1 800 m、2 200 m以及2 400 m赛程的比赛成绩两个赛季中存在显著差异.
Performance data on the population of Thoroughbreds racing in Hong Kong between September2015 and July 2017( n = 1 551) were acquired and used to estimate the difference of racing performance in two seasons. In this study,independent sample T test was adapted to test the difference of the same distance of racing performance of 1 551 horses. Two conclusions in this study are: 1) there were no significant differences in racing performance of 1 000 m and 2 000 m; 2) there were significant differences in racing performance of1 200 m,1 400 m,1 600 m,1 650 m,1 800 m,2 200 m,2 400 m.
