For many researchers the Rasch model provides a practical solution to data analysis in the social sciences. This work contends that Rasch measurement is the model of choice as it is the closest to realizing the sort of objective fundamental measurement so long revered in the physical sciences. The goals of this work are: to present an accessible overview of the basic properties and principles of Rasch analysis, that does not require a sophisticated statistical background; to demonstrate how Rasch analysis can be applied to a number of generic problems encountered by psychologists and educators; and to prepare readers for performing their own analyses and interpreting the results.
