摘要
统计整理了天津工业大学115个班级2 971名学生某工科数学课的期末考试成绩,得到了每个班级的平均成绩、成绩的中位数、最高分和最低分等4个成绩指标数据,计算了它们间的线性相关系数r、和谐性度量Spearman′sρ和Kendall′sτ.构造了综合考试成绩代表性和稳定性的新型评价指标.
Sumed up 2 971 final examination results of 115 class of a basic course in engineering mathematics of Tianjin polytechnic university.For each class extracted its lowest score,highest score,median score and average score etc.Calculated the linear correlation coefficient r and concordance measure of Spearman′s ρ 和 Kendall′s τ between them.Constructed a new comprehensive evaluation both representative and stability.
