LING-584 Statistics for Linguistics Research
Fall for 2017-2018
This course introduces basic design, measurement, analysis, and inference procedures used in applied linguistics quantitative research, with an emphasis on understanding and using statistics and on developing foundational skills with computerized statistical tools. More broadly, the course addresses a range of topics critical to the accurate and ethical use of quantitative methods in language studies, including: (a) the purposes and roles of research; (b) literature review and the generation of research questions; (c) study design strategies for gathering, organizing, and analyzing quantitative data; (d) the importance of accuracy (and error) in developing and using measures and other data elicitation procedures; (e) critical reading of research reports; and (f) current concerns with the use of statistical significance testing, the role to be played by power analysis, effect sizes, and confidence intervals, and the nature of ‘scientific research’.

Statistical techniques covered in this course include a variety of applications within the following broad categories:
• description
• correlation and prediction
• comparison of means
• comparison of frequencies
• effect sizes and confidence intervals
This list appears deceptively brief and simple—the accurate and effective use of related techniques requires understanding and careful planning. Therefore, the course addresses statistics from three perspectives: principles (logic and use), practice (how to calculate and interpret), and presentation (how to display and report). For each technique, the use of computerized tools is demonstrated, and students are afforded practice opportunities through analytic exercises.
