Administer the draft test to a group comparable to people who will be trained. Interview examinees to determine if they felt the test was appropriate. Identify "poor" items such as those answered incorrectly by many examinees. Score items (0,1) for each trainee in the instructed and uninstructed groups.A discrimination index of -1.0 means all of the low scorers got the item correct and all of the high scorers got it incorrect. Items with d’s close to 0 or with negative d’s ought to be eliminated from the test!

Summary "In this new, revised and enlarged edition, Discrimination and Disparities goes beyond its analysis--in the first edition--of the sources of disparities and the different kinds of discrimination. The students were also given one period of instruction, and a table of specifications was made for their unit of learning. There were 32% "masters" (achieving 80% correct) and 68% "non-masters" within the sample on the multiple-choice test. The students were also given one period of instruction, and a table of specifications was made for their unit of learning. There were 32% "masters" (achieving 80% correct) and 68% "non-masters" within the sample on the multiple-choice test. 1/30/2019 4 Item 1. Calculating Difficulty and Discrimination •Top scoring group (n = 25): 20 got it correct, or 80% •Middle group (n = 50): 20 got it correct •Lowest scoring group (n = 25): 15 got it correct, or 60% •Difficulty level:Add the total who got the item correct - 20+20+15 = 55, and divide by the number of students, 100the roc analysis ( table 2 and fig. 1) showed that mcq consistently had very good level of discriminative ability as the value more than 0.8. 13 on top of that its sensitivity and specificity values were more than 80%, indicating good level of ability to predict and discriminate passed and failed students. 13 in other hand, long case demonstrated …The interpretation of High-Low Discrimination is similar to the interpretation of correlational indices: positive values indicate good discrimination, values near zero indicate that there is little discrimination, and negative discrimination indicates that the item is easier for low-scoring participants.An item that everyone gets correct or that everyone gets incorrect, as shown in Tables 1 and 2, will have a discrimination index equal to zero. Table 7 illustrates that if more students in the lower group get an item correct than in the upper group, the item will have a negative D value and is probably flawed.
