The chapters in this innovative book introduce the quantitative analysis of linguistic survey data with specific reference to the Linguistic Atlas of the Middle and South Atlantic States (LAMSAS). Topics covered include: the relation of sociolinguistics to the original conception of LAMSAS; the adaptation of LAMSAS to the needs of computerization and the research methods envisioned; the mechanics involved in computerizing LAMSAS; how to handle and analyze the data in the database management system; the creation of categories for analysis; and the logic of statistical testing.
