Evaluating and Conducting Research in Audiology is the first research methods textbook that is specific to the field of audiology and designed to serve as an academic textbook for audiology graduate students. This text can also be accessible for audiology practitioners who are interested in clinical and applied research. The comprehensive coverage includes materials for multiple courses within audiology degree programs, including research methods, analysis of professional literature, evidence-based practice, and capstone research projects.

The text provides knowledge that is required in evaluating, conducting and disseminating research. The book is separated into three sections: (a) research methods; (b) evidence-based practice; and (c) conducting and disseminating research. Together, these sections provide a detailed coverage of the of research methods that are relevant to conducting research, particularly in the field of Audiology.
