Critical Index of Difficulty for Different Body Motions: A Review

Journal of Motor Behavior, 2015
K.-C. Gan and E. R. Hoffmann (1988) demonstrated that there is a clear boundary between values of Fitts' index of difficulty (ID) below which movements may be made without ongoing path corrections; above this value it was necessary to use corrections to hit a target of high ID.

Difficulty index of a question paper: A new perspective

2012 IEEE International Conference on Engineering Education: Innovative Practices and Future Trends (AICERA), 2012
Assessment of learning reflects the performance of an academic system. In reality, this performance is the cumulative impact of learning in each course of the program. Hence on completion of delivering a course in terms different components, it becomes important to understand the outcome produced, the knowledge and skills acquired by the students.

Limb-Target Control Increases With Effective Index of Difficulty

Journal of Motor Behavior
Researchers have investigated the sensorimotor mechanisms that result in Fitts' law. One approach has been to analyse movement trajectories during Fitts' tasks to reveal the processes that occur during movement preparation and execution. We used trajectory analysis in the current study to investigate how limb-target control contributed to Fitts' law ...

Performing Under Difficulty: The Magical Pressure Index

2019
This chapter introduces an interesting concept of measuring performance of cricketers considering the match situation under which the player performed. The difficulty level, under which the team is performing, is quantified introducing a measure called as the pressure index in the chapter. The pressure index is an inclusive measure that can be utilized

Predicting the difficulty of a transvenous lead extraction procedure: Validation of the LED index

Journal of Cardiovascular Electrophysiology, 2017
AbstractIntroductionA lead extraction difficulty (LED) score was proposed to predict the difficult transvenous lead extraction (TLE) procedures, defined by means of the fluoroscopy time. The aim of this study was to validate the estimation model based on the LED index above 10 on an independent data set of TLE cases.MethodsConsecutive patients ...

The Relative Difficulty Ratio—a Test and Item Index

Educational and Psychological Measurement, 1981
The Relative Difficulty Ratio (RDR) was developed as an index of test or item difficulty for use in situations in which raw score means or item p-values are not directly comparable because of chance score differences. Computational RDR are described. Data from the literature are used to illustrate applications of the RDR at both the test and item level.

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
