Assuming no prior knowledge, this text provides a concise, practical and accessible introduction to using, analysing and interpreting statistics and methodologies in empirical work using R or JASP. It takes an activity-based approach, in which students are first stimulated to consider a problem or question and find their own solution before the conventional way of solving that problem or question is introduced. 'How To' guides on R and JASP, which take students step-by-step through statistical analyses and practical assignments, are available on the book's companion website. This book will be an invaluable resource for undergraduate and postgraduate students of Applied Linguistics.
