LING 507 Statistical Analaysis for Linguists Spring 2013

Students will learn to use the statistical methods common in linguistics and related fields in order to apply them in the design and analysis of their own research. Methods covered will include ANOVA, ANCOVA, correlation, regression, and non-parametric tests, as well as some specialized analyses such as Multidimensional Scaling Analysis. The course will focus primarily on methods and problems of psycholinguistic, phonetic, and sociolinguistic research. Discussion of the statistical analyses in published articles in these areas will form a substantial part of the course, and application of the methods covered in the course to the students' own research will also be discussed. The course will include instruction in use of statistical software packages.
