differential item functioning (dif) biais de mesurage (DIF) Explanation: "Stéphane Vautier, Université de Toulouse, France http://w3.octogone.univ-tlse2.fr/vautier/ - Translate this page La question de la détection de biais de mesurage (Differential Item Functioning) est aussi abordée au cours de cette journée. Date et lieu : le vendredi 28 mai ..." " Differential item functioning (DIF), also referred to as measurement bias, occurs when people from different groups (commonly gender or ethnicity) with the same latent trait (ability/skill) have a different probability of giving a certain response on a questionnaire or test.[1] DIF analysis provides an indication of unexpected behavior of items on a test. An item does not display DIF if people from different groups have a different probability to give a certain response; it displays DIF only if people from different groups of same underlying true ability have a different probability of giving a certain response. Common procedures for assessing DIF are Mantel-Haenszel, item response theory (IRT) based methods, and logistic regression.[2]" http://en.wikipedia.org/wiki/Differential_item_functioning |
