Abstract
The study examined the analysis of differential item functioning in Economics multiple choice items administered
by West African Examination Council using logistic regression model. Ex-post factor research design was employed
for the study. The population for the study comprised 2,985 Senior Secondary School Three (SS3) Economics
students in Nsukka education zone of Enugu State. Sample size of 339 SS3 Economics students was used for the
study. A 50-item test of 2018 Economics multiple choice questions developed by West African Examination
Council (WAEC) was used to collect pertinent data for the study. Reliability coefficient of 0.87 was obtained using
Kudder-Richardson (K-R) 20 formula. Logistic Regression procedure was used to analyze the data collected from
the study. The findings of the study revealed that out of 50 items in 2018 WAEC Economics questions, 31 items
which represent 62% of the test items displayed significant location DIF at 0.05 level of significance. Among the 31
items, 27 items representing 54% were identified to exhibit significant location DIF in favour of urban school
students while only 4 items representing 8% differentially functioned in favour of rural school students. The study
recommended among others based on the study that examination bodies such as West Africa Examination Council,
National Examination Council among others should use DIF for their pilot study using school location and other
possible groupings like gender to ensure fairness in their test items.

Key words: Differential Item Functioning (DIF), Location, Item Bias, Economics, Logistic Regression Procedure
