摘要
针对立定跳远中出现的预摆次数对成绩的影响进行探讨,将预摆一次的成绩和预摆两次的成绩的原始数据利用统计学进行认真核对、整理、分类、列表、比较,然后对获得的资料采用平均数、标准差、假设检验的统计,得出在立定跳远中预摆的次数愈少成绩愈高这一结论.
This paper probes into whether the times of pre-jump hand-swing can affect the grade of stationary long jump. Original data of the grades with only one pre-jump hand-swing and those with two times of pre-jump hand-swing are carefully checked, sorted, classified, charted and compared through the method of statistics. And then with an evaluation of the average, standard difference, and hypothesis testing of these data, this paper deduces a conclusion that the least times of pre-jump hand swing achieves the best grade in stationary long jump.
