Wb. Walstad et D. Robson, DIFFERENTIAL ITEM FUNCTIONING AND MALE-FEMALE DIFFERENCES ON MULTIPLE-CHOICE TESTS IN ECONOMICS, The Journal of economic education, 28(2), 1997, pp. 155
Item Response Theory (IRT) methods were applied to data from the natio
nal norming of the Test of Economic Literacy (TEL) to identify test qu
estions with large male-female differences; economic ability was contr

ession analysis showed a significant decrease in the magnitude of the
gender difference, although a difference was still present.
