对男大学生上肢力量类测验项目的等值研究

A Study on the Equating of Upper-body Strength Tests for Male College Students

为建立两上肢力量测验(引体向上、双杠屈臂)评分评价标准间等值关系式,并比较不同等值方法对等值准确性和稳健性的影响,对453名男大学生分别进行了两项测验,每项测验间隔一周,对其进行线性等值、一般的等百分位等值和平滑的等百分位等值。结果表明:①在进行平滑等百分位等值时,平滑模型的选取应视不同的测验项目而定。②在对两种上肢力量类测验等值的三种方法中,线性等值方法的效果最好。

To determine the equivalence of the two upper-body strength tests （pull-up and push-up） for evaluation standards and compare different equating methods that may influence the accuracy and stability of equivalence ,two tests are administered to 453 male college students. The two tests are conducted separately with one week apart, and the testing methods include linear equating, the unsmoothed and smoothing equi-percentile equating. The following results are obtained： ① In smoothing equi-percentile equating, the smoothing model should be chosen according to different items in tests. ② Among the three equating methods of upper-body strength tests ,the linear equating functions the best.
