ABIL: An Interactive Microcomputer Program for Calculating Score Ability Estimates from Item Difficulty Statistics

A computer program is described which generates the number-correct to logit-scaled-score (ability-score) conversion table for a test composed of items precalibrated using Rasch procedures. A graph of the test information function is also produced. The program is written in BASIC for the Apple II Plu...
