Variability in Reliability Coefficients and the Standard Error of Measurement from School District to District.
Feldt, Leonard S.; Qualls, Audrey L.
Applied Measurement in Education, v12 n4 p367-81 1999
Examined the stability of the standard error of measurement and the relationship between the reliability coefficient and the variance of both true scores and error scores for 170 school districts in a state. As expected, reliability coefficients varied as a function of group variability, but the variation in split-half coefficients from school to school was relatively modest. (SLD)
