حداقل نمره در روش ننقشه سوال
Her study included four standard setting comparisons, and the item mapping cut score was lower than the Angoff in each comparison by between 9% and 19% of the total items on the examination.
First, I determined whether the two Angoff cut scores and the two item mapping cut scores were significantly different using a two-sample z test for difference of item difficulty.
Z tests for difference of item difficulty were used to compare the Hofstee cut score to the Angoff and item mapping cut scores.
However, it was significantly different from the group 1 item mapping cut score (z = 2.54, p = 0.01) and the group 2 item mapping cut score (z = 3.58, p
2(2) = 3.26, p = 0.20), with a mean rank of 20.1 for the Angoff cut score, 23.7 for the group 1 item mapping cut score, and 16.3 for the group 2 item mapping cut score.
