Variability in Reliability Coefficients and the Standard Error of Measurement from School District to District.

Peer reviewed

Feldt, Leonard S.; Qualls, Audrey L. – Applied Measurement in Education, 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…

Information Retention as a Function of the Number of Intervals and the Reliability of Continuous Variables.

Peer reviewed

Schiel, Jeffrey L.; Shaw, Dale G. – Applied Measurement in Education, 1992

Changes in information retention resulting from changes in reliability and number of intervals in scale construction were studied to provide quantitative information to help in decisions about choosing intervals. Information retention reached a maximum when the number of intervals was about 8 or more and reliability was near 1.0. (SLD)
