IAPG: An Item Analysis Program for Questionnaire-Type Test Instruments.

Abstract

IAPG (Item Analysis Program, General) is a versatile series of item analysis computer programs. The input consists of responses to items for which the correctness or incorrectness of a particular alternative is not the same for all respondents. The comprehensive statistical/mathematical methodology that comprises IAPG enables the user to optimize the composite validity of a test instrument subject to certain restrictions delineated in this report and perform complex item analysis procedures. This report documents the input/output and mathematical/statistical methodology to be used in executing and interpreting the results of the IAPG group of programs. It contains the technical details that are necessary for the user to take complete advantage of the analytical capabilities of IAPG. This information includes computational formulas, control and data card descriptions, file layouts, printed output samples, diagnostic messages, and examples of run time. (Author)
