## Description

*Quantitative Methods in Linguistics*offers a practical introduction to statistics and quantitative analysis with data sets drawn from the field and coverage of phonetics, psycholinguistics, sociolinguistics, historical linguistics, and syntax, as well as probability distribution and quantitative methods.

- Provides balanced treatment of the practical aspects of handling quantitative linguistic data
- Includes sample datasets contributed by researchers working in a variety of sub-disciplines of linguistics
- Uses R, the statistical software package most commonly used by linguists, to discover patterns in quantitative data and to test linguistic hypotheses
- Includes student-friendly end-of-chapter assignments and is accompanied by online resources at available in the 'Downloads' section, below

## Reviews

*Mark A Pitt, Ohio State University*

"Johnson's book is a catalyst for change in linguistics. Increasingly, the subjective, impressionistic data collection method is being replaced by objective, quantitative measurements. This book serves an important function in this process leading students step-by-step toward using statistical methods to analyze complex data." *Chilin Shih, University of Illinois at Urbana-Champaign*

"This rich and rewarding textbook is a must-read for all students and researchers who wish to follow the new wave of sophisticated empirical models and methods now sweeping the field of linguistics from phonetics to syntax and semantics." *Joan Bresnan, Stanford University*
