This book provides a concise yet thorough introduction to methods that linguists can use to study patterns of sentence acceptability in speech.Experimental Syntax shows how to design, execute and analyze an appropriate survey experiment for a well-formed question about a matter of fact relative to sentence acceptability. The book also examines variability and demonstrates a method by which an investigator can make principled decisions as to whether two or more informants who use atypical dialects are using the same atypical dialect.
