Standard Errors of the Tucker Method for Linear Equating under the Common Item Nonrandom Groups Design. ACT Technical Bullegin Number 44.
Kolen, Michael J.
Large sample standard errors for the Tucker method of linear equating under the common item nonrandom groups design are derived under normality assumptions as well as under less restrictive assumptions. Standard errors of Tucker equating are estimated using the bootstrap method described by Efron. The results from different methods are compared via a computer simulation as well as a real data example based on test forms from a professional certification testing program. (Author/PN)
