This article introduces readers to the data analytic sub-paradigm of nonparametric statistics. The authors begin with an explanation of how and under what circumstances nonparametric statistics are used, then describe specific nonparametric techniques which are commonly used in social science research. Examples from the contemporary rehabilitation literature are provided throughout the article.
The article examines reliability as a key component of the psychometric properties of tests and inventories. What is reliability, types of reliability, why is reliability important, and other reliability issues are addressed in a manner that will help Work readers to better understand and apply psychometric considerations in the context of rehabilitation research. The authors contend that reliability is an essential condition for the psychometric soundness of measurement instruments that are used in rehabilitation research and practice.
This article examines applications of multiple regression in rehabilitation research. The authors address the logic and assumptions of correlational research, annotated with examples from the contemporary rehabilitation and allied health literature. As a means of testing relationships between a set of independent variables and one dependent variable, multiple regression is presented as a flexible and useful data analytic strategy.
The article describes the components and composition of journal articles that report empirical research findings in the field of rehabilitation. The authors delineate technical writing strategies and discuss the contents of research manuscripts, including the Title, Abstract, Introduction, Method, Results, Discussion, and References. The article concludes with a scale that practitioners, manuscript reviewers, educators, and students can use in critically analyzing the content and scientific merits of published rehabilitation research.
