运用模糊数学和数理统计理论,以各级评测指标及主要观测点的观测值是否偏离正常的取值区间为评判要点,着重考察试卷对正常区问的偏离程度以严格控制试卷的异常状况,构建了评测试卷命题质量的科学而适用的数学模型.
運用模糊數學和數理統計理論,以各級評測指標及主要觀測點的觀測值是否偏離正常的取值區間為評判要點,著重攷察試捲對正常區問的偏離程度以嚴格控製試捲的異常狀況,構建瞭評測試捲命題質量的科學而適用的數學模型.

A scientific and applicable mathematical model is constructed by using fuzzy theory and mathematical statistics. The evaluation point is whether the index at all levels and the value of main observation point deviate from the normal range of values. The review on degree of deviation is emphasized so as to avoid its high liberation.
