Abstract

This is a guide to using Quest. Quest offers a comprehensive test and questionnaire analysis environment by providing a data analyst with access to the most recent developments in Rasch measurement theory, as well as a range of traditional analysis procedures. It includes an easy to use control language with flexible and informative output. Quest can be used to construct and validate variables based on both dichotomous and polychotomous observations. It scores and analyses such instruments as multiple choice tests, Likert type rating scales, short answer items, and partial credit items.
