摘要
本文在合理假定的基础上，借助于分析技巧，推出了教育测量学中信度系数的上下界估计。该上下界是著名的kuder－Richardson公式20[4]及Cronbach阿尔法系数[3]的推广。
Under some reasonable assumptions, using some elementary analytic techniques, the author obtains lower and upper bounds for the reliability coefficients in the Educational Measurement,thus generalizing the well - known Kuder - Richardson's Formula 20 and the Cronbach' alpha Cronbach's alpha coofficient method.
