"The ability to use statistics is essential for anyone wishing to analyse data from language. Language teaching practitioners are increasingly being asked to assess their students' language ability. This book, written by one of the leading figures in the field of language assessment, deals with the complexity of statistical analysis in an accessible and comprehensive manner. The book provides: help in selecting the correct procedure; clear, step-by-step instructions for statistical procedures; and guidance in interpreting the results." (Book Cover)
