英文摘要 |
This study applies the Mantel-Haenszel procedure to investigate DIF that generated by a cognitive diagnostic model, DINA. Three matching criteria are used to calculate the Mantel-Haenszel chi-square test statistic: the total scores (MH-T), the attribute profile of examinees (MH-P) and the attribute profile of items intended to be tested (MH-I). Simulation studies include factors such as item parameters, attribute distributions, sample sizes, and the amount of DIF. Results show that the MH-I method has great powers in detection DIF while controlling a reasonable type I error rate. |
