One popular choice among researchers and analysts is SPSS, or Statistical Package for the Social Sciences.An item analysis is a valuable, yet relatively easy, procedure that teachers can use to answer both of these questions. To determine the difficulty level of test items, a measure called the Difficulty Index is used. This measure asks teachers to calculate the proportion of students who answered the test item accurately. Item response theory. In psychometrics, item response theory ( IRT) (also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables.Item analysis is a process which examines the responses to individual test items or question in order to assess the quality of those items and the test as a whole.

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 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.
