The relationship of the Alpha coefficient with the congeneric test,the parallel test and the essential-τ-equivalent test,and the relationship among the three tests were reviewed.
本文从α系数与同质性测验、平行测验和基本τ-等价测验间的关系及三种测验间的关系入手,分析了α系数作为测验同质性信度估计的局限性;根据J reskog给出的信度定义(α系数),讨论了λ系数与α一致性信度、Guttman下限之间的关系,说明了在测验同质的前提下,λ系数在估计测验内部一致性时与α系数相比的优点。
