Two Generalizations of the Item Discrimination Index to Multi-Score Items

The Journal of Experimental Education, 1971
Two general item analysis indices which apply to multi-score items are developed as generalizations of a popular index applicable to dichotomous items. The indices of discrimination are of two types: one based on differential difficulty and the other on net number of positive discriminations. The usefulness and limitations of each are discussed.

A DISCRIMINATION INDEX FOR ITEMS IN INSTRUMENTS USING GROUP RESPONSES

Journal of Educational Measurement, 1971
Item discrimination for instruments used to measure characteristics by means of group responses is stressed. It is argued that a percentage of the total sum of squares which is due to groups can appropriately be used as an index of item discrimination.

Superior discrimination of the Risk Analysis Index compared with the 5-item modified frailty index in 30-day outcome prediction after anterior cervical discectomy and fusion

Journal of Neurosurgery: Spine, 2023
OBJECTIVE The objective of this paper was to compare the predictive ability of the recalibrated Risk Analysis Index (RAI-rev) with the 5-item modified frailty index-5 (mFI-5) for postoperative outcomes of anterior cervical discectomy and fusion (ACDF).

Test Item Analysis and Relationship Between Difficulty Level and Discrimination Index of Test Items in an Achievement Test in Biology

Paripex - Indian Journal Of Research, 2012
Current piece of work is focussed on the analysis of test items constructed in the subject of Biology for class IX. It involved the analysis of difficulty level and discrimination power of each test item. There were 120 objective type questions in the achievement test and was administered on a sample of 500 students from government and private schools.

Relationships Between the Item Difficulty and Discrimination Indexes

Educational and Psychological Measurement, 1979
The dependence of the item discrimination index (D) on the item difficulty index ( p), and the relationship of D and p to the phi coefficient (ϕ) are delineated. A table of critical values of D for significance at the .10 and .05 levels, with the number of examinees in the upper group (n, ) on total test score ranging from 10 to 25 and p ranging from .

An Attribute-Specific Item Discrimination Index in Cognitive Diagnosis

2019
There lacks an item quality index as a measure of item’s correct classification rates of attributes. The purpose of this study is to propose an attribute-specific item discrimination index as a measure of correct classification rate of attributes based on a q-vector, item parameters, and the distribution of attribute patterns.

Transforming Teaching-Learning Culture by Appropriate Use of Discrimination Index in Item Analysis

2017
The current policies on use of discriminative index (DsI) hinge on the teaching-learning culture of stratifying the class based on academic performance. Such a distinction may be acceptable to norm-referenced tests (NRTs) where the examinees are unselected and selection of the good from the bad students occurs by internal comparison of students’ score.
