We can calculate the difficulty index (cell T23) using the formula =ITEMDIFF(T4:T21), the discrimination index (cell T24) using the formula =ITEMDISC(T4:T21,U4:U21,1/3) and the point-biserial …Item validity and item discrimination index in Table 1, Table 2, Table 3, Figure 1, Figure 2 dan Figure 3 were the results from raw data processing with equation (1) and equation (2). Table 1.Results: The difficulty index of MCQ ranged from 0.67 to 0.79, which is considered as optimal level. The difficulty index for Long Case ranged from 0.89 to 0.91, which is con-sidered as less optimal level. The MCQ demonstrated higher discrimination index (0.58–0.76) than the long case (0.20–0.23), suggesting the MCQ was better able to ...

Index Target sensor Formula; UI ... (TD), and the Spectral Discrimination Index (SDI), which have been widely used in similar studies (Deng and Wu, 2012, Nguyen et al., 2021). The value ranges of JMD and TD are [0, 2) and [0, 2), respectively, and SDI does not have a fixed value range. The evaluation criterion is the larger the JMD, TD, …When we subtract the proportion of low-scoring students who got an item right from the proportion of high-scoring students who got it right, then the remainder becomes the …Quick Reference. In psychometrics, the degree to which a test yields different scores when applied to different criterion groups; specifically, the degree to which an item in an attitude scale, or the scale as a whole, yields different scores when it is applied to people holding different attitudes towards the attitude object in question.However, the correlation between the discrimination index and the number of NFDs was insignificant (r = 0.055; P = 0.135). The findings revealed that NFDs inversely affected the test quality of items.

The model of discrimination performance discussed in the previous file assumes that when listeners do not hear a difference, or are not sure, they respond "same" or "different" randomly, so that performance is at chance. But there is no guarantee that listeners will do that.

A discrimination index was calculated for the test trial using the following formula: discrimination index = (novel object time/total exploration time for all four objects) × 100. The discrimination index was analyzed by a one-way ANOVA and by t -tests comparing each group to chance performance (25% in this study).for item discrimination, acceptable values are 0.2 or higher; the closer to 1 the better in case the total Cronbach’s Alpha value is below the acceptable cut-off of 0.7 (mostly if an index has few items), the mean inter-item-correlation is an alternative measure to indicate acceptability; satisfactory range lies between 0.2 and 0.4For Question #1, this would be 8/10 or p=.80. Determine the Discrimination Index by subtracting the number of students in the lower group who got the item correct from the number of students in the upper group who got the item correct. Then, divide by the number of students in each group (in this case, there are five in each group).
