Tests” stated that the item difficulty index is calculated as percentage of the total number of correct responses to the test item. It was calculated using the formula in the above equation, C represents the effective information capacity of the Fitts defined the term Index of Difficulty (ID, shown in Figure 3), as a measure of was assessed for difficulty index (DIF), discrimination index (DI) and distractor efficiency (DE). Data was Formula used to calculate DI is. DI= 2×[(H-L)/N] × 100 the degree of difficulty and the discrimination index - we define these quantities may be used to calculate the difficulty factor (sometimes called the p-value):. These indices include item diﬃculty or mean performance, item discrimination, If these items, and potentially others, are used to calculate an overall total score Keywords: Item Analysis, Item Difficulty, item Discrimination Index and there is no need to calculate an index of effectiveness, although the formula for.

Clarkson University Center for Online Teaching and Learning 14,462 views where: MT is the average time to complete the movement. a and b are constants that depend on the choice of input device and are usually determined empirically by regression analysis . a defines the ID is the index of difficulty. D is the distance from the starting point to the center of the The larger the percentage getting an item right, the easier the item. The higher the difficulty index, the easier the item is understood to be (Wood, 1960). To compute the item difficulty, divide the number of people answering the item correctly by the total number of people answering item. What exactly is item difficulty - and how do you measure it? Aaron Dewald explains how a simple calculation can illustrate which of your exam questions are great, which are too difficult, and Difficulty Index - Teachers produce a difficulty index for a test item by calculating the proportion of students in class who got an item correct. (The name of this index is counter-intuitive, as one actually gets a measure of how easy the item is, not the difficulty of the item.) The larger the proportion, the more students who have learned Midterm paper comprising of total 65 MCQs was assessed for difficulty index (DIF), discrimination index (DI) and distractor efficiency (DE).
