| 摘 要： | 成绩正态分布的观点不是完全成立的,大多数情形下成绩分布是负偏态的.根据当前的教学要求,利用三次Hermite样条和B-spline构造了新的考试成绩标准分布函数,并分析了实际的例子.最后,对成绩分布函数给出了建议.

| Abstract: | The view of normal distribution of examination performance is not always established,while the distribution of examination performance is negative skewness distribution in the most situations.Based on the current teaching requirements,a new standard distribution of examination performance was constructed with cubic Hermite splines and B-spline,and some practice cases were analyzed.Finally,some suggestions were provided. |
