Estimating Reliability under a Generalizability Theory Model for Test Scores Composed of Testlets.
Lee, Guemin; Frisbie, David A.
Applied Measurement in Education, v12 n3 p237-55 1999
Studied the appropriateness and implications of using a generalizability theory approach to estimating the reliability of scores from tests composed of testlets. Analyses of data from two national standardization samples suggest that manipulating the number of passages is a more productive way to obtain efficient measurement than manipulating the number of items within each passage.
