This module aims to develop students’ understanding of research design and statistical methods used in speech and language research and in the evaluation of therapy for communication disorders. It provides direct experience and knowledge of methods used to investigate and evaluate clinically relevant topics. Students will learn how to select and apply a range of statistical analysis methods in experimental research by exploring literature and understanding the importance of the various approaches for different circumstances. The course has a strong practical and literature-based foundation.

AIMS
