Toward More Robust Inferential Procedures for Coefficient Alpha under Sampling of Both Subjects and Conditions.
Peer reviewed Peer reviewed
Hakstian, A. Ralph; Barchard, Kimberly A. – Multivariate Behavioral Research, 2000
Developed a sample-based nonanalytical degrees-of-freedom correction factor for situations sampling both subjects and conditions with measurement data departing from essentially parallel form. Assessed the application of this correction factor through a simulation study involving data sets with a range of design characteristics and manifesting…

The Effects of Sampling Model on Inference with Coefficient Alpha.
Peer reviewed Peer reviewed
Barchard, Kimberly A.; Hakstian, A. Ralph – Educational and Psychological Measurement, 1997
The distinction between Type 1 and Type 12 sampling in connection with measurement data is discussed, and a method is presented for simulating data arising from Type 12 sampling. A Monte Carlo study is described that shows conditions under which precise confidence level control under Type 12 sampling is maintained. (SLD)
