Schmidgall, Jonathan – Applied Measurement in Education, 2017
This study utilizes an argument-based approach to validation to examine the implications of reliability in order to further differentiate the concepts of score and decision consistency. In a methodological example, the framework of generalizability theory was used to estimate appropriate indices of score consistency and evaluations of the…

Yin, Yue; Shavelson, Richard J. – Applied Measurement in Education, 2008
In the first part of this article, the use of Generalizability (G) theory in examining the dependability of concept map assessment scores and designing a concept map assessment for a particular practical application is discussed. In the second part, the application of G theory is demonstrated by comparing the technical qualities of two frequently…

Kane, Michael – Applied Measurement in Education, 1996
This overview of the role of error and tolerance for error in measurement asserts that the generic precision associated with a measurement procedure is defined as the root mean square error, or standard error, in some relevant population. This view of precision is explored in several applications of measurement. (SLD)
