of Item Difficulties,” Psychometrika, 1952, 18, 181-194.)

22. ITEM ANALYSIS
DISCRIMINATION FACTOR/INDEX
The discriminant factor is a correlation
between students that answer this question
correctly and how well those students
performed on the test overall. Expressed as a
decimal between -1 and +1, a positive
discriminant factor indicates that students
that did well on this question did well on the
overall test.
A strong negative value may indicate a poorly
written question or incorrectly keyed answer.
