- Note: Following the convention on effect sizes for DIF described by Magis et al., effect sizes below the medium threshold are classed as negligible rather than small. Blanks indicate no items of that magnitude. “Total” refers to total number of significant DIF tests. As some items exhibited DIF for both ethnicity and sex, the total number of items identified as problematic is slightly lower
