the cut score is set within this difficulty range. the cut score is usually interpreted as falling at the top end of that column — so within the range.

Question 8

a test has 50 items grouped into 10 columns based on IRT difficulty. A panelist asks whether all items in Column 6 are “equally difficult.” What is the best response?

Answer 8

not exactly — they fall within a shared difficulty range but may vary slightly

Question 9

the main goal of discriminant analysis is to:

Answer 9
