Définition(s)

  • Differential item functioning (DIF) is the preferred psychometric term for what is otherwise known as item bias. An item displays DIF when test takers possessing the same amount of an ability or trait, but belonging to different subgroups, do not share the same likelihood of correctly answering the item.
