Books
	Themistocleous Charalambos (2015). Experimental Design and Statistics in Linguistics. Using R (In Greek). Athens: Ion. ISBN:978-960-508-187-4. This book is an introduction to experimental methodology and statistics using R and aims: to present the basic principles of experimental methodology and experimental design. to introduce statistics and their application to language problems. to introduce R, a programming language with specialized functions for statistical analysis. The experimental methodology concerns the systematic and organized examination of a research object. The research begins with identifying a problem, the definition of the more specific research questions, and the formulation of specific experimental hypotheses. In this book, we examine how statistical analysis works, the theoretical principles that govern it, and how it relates to experimental methodology. The book aims twofold to teach how statistical tests are performed and present the reasoning that regulates them. Therefore, an attempt was made to make this book as pedagogical and easy to use as possible. Examples based on linguistics and language research have been used for this purpose.
