Item analysis typically focuses on four major pieces of information: test score reliability, item difficulty, item discrimination, and distractor information. No single piece should be examined independent of the others. In fact, understanding how to put them all together to help you make a decision about the item’s future viability is critical. dependable and simple discrimination index by comparing some popular discrimination indices based on different internal criteria (i.e., the subtest-total score and the entire-test-total score). The acquisition and comparison of the discrimination indices were fulfilled by means of modern computer programs—Lertap5 and SPSS.The Discrimination Index (D) is computed from equal-sized high and low scoring groups on the test. Subtract the number of successes by the low group on the item from the number of successes by the high group, and divide this difference by the size of a group. The range of this index is +1 to -1.
