Abstract
This chapter provides the first steps in the construction and interpretation of Wright maps. These maps have revolutionized the development and use of instruments and the communication of research results in health, education, psychology, and business. Readers are guided through a “must do” construction of a Wright map using the self-efficacy data. In this hands-on activity, readers practice reading numerous Winsteps tables while developing a better sense of what “going up” or “going down” the Wright map means for items and persons. Readers are also introduced to methods of examining the strengths and weaknesses in their measurement instrument in terms of item distribution. Following the construction of the Wright map, readers learn where Winsteps provides a Wright map. The chapter finishes up with a summary discussion between our two students, Keywords and Phrases, Quick Tips, Data Files, References, and Additional Readings. As in almost all chapters, sample analyses are used to reinforce the chapter topic.
