It also aimed to find out the extent of agreement between the two methods of detecting (DIF) according to gender variable.

Here are the most important findings:
Uniform DIF was detected in (3) items, equals (6.8% ) using (MH) method; two items, favouring male group, and one item, favouring female group, but when using the (RSAI) method, a uniform DIF was detected in two items, equals (4.5% ); one item, favouring male group, and one item, favouring female group.

The percentage of agreement between the (MH) and the (RSAI) methods was high, as the two methods reveal two items at a rate of (66.6% ) out of (3) items that showed (DIF) due to gender variable.
