Random or fixed testlet effects : a comparison of two multilevel testlet models

Beretvas, Susan Natasha (contributor) - 2010

This simulation study compared the performance of two multilevel measurement testlet (MMMT) models: Beretvas and Walker’s (2008) two-level MMMT model and Jiao, Wang, and Kamata’s (2005) three-level model. Several conditions were manipulated (including testlet length, sample size, and the...
