累进计分法中目前采用较多的方法是利用抛物线方程的公式Y=KD2-Z求的方程公式得累进分值,通过对学生100m成绩采用同一公式不同的Y取值方法制定出100m成绩评分表进行比较,在使用中要注意样本的大小不能盲目地一概选用X±3s,应先考虑利用百分数所对应的u值,Y分值应随所需控制成绩人数百分数临界分值确定,这样才能制作出满意的累进计分表。
Progressive scoring method currently used more is the use of the formula of the equation parabolic equation Y = KD2-Z progressive scores were obtained through the student’s 100m results using the same formula different Y values to develop a score of 100m Table to be compared, in use should pay attention to the size of the sample can not blindly choose X ± 3s, you should first consider the use of the percentage corresponding to the u value, Y score should be controlled scores with the percentage of the number of critical scores to determine, so as to Produce a satisfactory progressive scoring table.
