Simultaneous DIF Amplification and Cancellation: Shealy-Stout's Test for DIF
Abstract
The present study investigates the phenomena of simultaneous DIF amplification and cancellation and SIBTEST's role in detecting such. A variety of simulated test data were generated for this purpose. In addition, real test data from various sources were used. The results from both simulated as well as real test data, as Shealy and Stout's theory suggests, show that the SIBTEST is effective in assessing the DIF amplification and cancellation (partially or fully) at the test score level. Finally, methodological and substantive implications of DIF amplification and cancellation are discussed. SIBTEST, DIF, Item bias, Test bias, Bias amplification, Bias cancellation.
