This measure asks teachers to calculate the proportion of students who answered the test item accurately. Item response theory.

Statistical analysis also helps to identify items that may have slipped through item review boards; item defects can be hard to identify. The objective of qualitative and statistical review isaveraging. For example, in psycholinguistics, people would average over items for a subjects-analysis (each data point comes from one subject, assuring independence), and then they would also average over subjects for an items-analysis (each data point comes from one item). There's a whole literature on theItem1 is extremely difficult; no one got it right! For polytomous items (items with more than one point), classical item difficulty is the mean response value. That is, if we have a 5 point Likert item, and two people respond 4 and two response 5, then the average is 4.5. This, of course, is mathematically equivalent to the P value if the ...An item may have a high p value (most students had the right answer) but a low discrimination index (high and low groups both answered item correctly). OR. Because students were not instructed on the concept. An item may have a low p value (item was difficult), but is an important concept to the field. Or took the test before the end of program.In the example above – item 1 has a mean of 60% i.e. 60% of all students got it right. It also has a good Discrimination Index (DI) of 0.4 meaning that this item could be used as a ranking question to help separate the stronger from the weaker candidates.
