Course Syllabus

Abstract

The course is devoted to modern methods of data analysis, as applied to linguistic data, including methods of statistical inference and explanatory data analysis with visualizations. We begin with theoretical background in mathematical statistics and discuss limitations of statistical methods and their applicability to linguistical problems. From practical point of view, we use R system to do actual analysis with real datasets. We also discuss different visualization techniques using popular library ggplot2.
Learning Objectives

Learning Objectives

  • Within this course you will: ● learn about the principal steps of a quantitative research in linguistics; ● learn about the possibilities and limitations of quantitative approaches as applied to different research questions; ● learn to formulate research questions and develop them into testable hypotheses; ● explore the possibilities of data collection and different approaches to sampling; ● learn to evaluate the quality of a quantitative approach; ● study the most common corpus, experimental, and mixed design of the linguistic studies and learn to evaluate research plans, discover and prevent the associated threats to data validity; ● practice in preparing your quantitative data for analysis, evaluating the quality of your data; treating missing data; ● learn about the possibilities and limitations of conventional statistical techniques and criteria, as well as some popular contemporary multivariate statistical methods; ● learn to choose and apply in practice a set of appropriate statistical tests for your research question.

Assessment Elements

  • non-blocking Домашние задания
  • non-blocking Подготовка индивидуального исследовательского проекта
  • blocking Устный экзамен
    The student is expected to prepare the final project in a written form as electronic document. The exam is conducted in the form of oral defense of the final project. The Exam Score measures the overall quality of the final project. It is integer number from 0 to 10. 
The Final Score is obtained from the following formula: Final Score = 0.6 × (Homework Score) + 0.4 × (Exam Score). Exam is conducted on Zoom platform, according to schedule that will be published using official telegram channel of the course. Link to Zoom meeting will be published there as well. First retake is conducted like exam. Second retake is conducted in form of written test. Connectivity problems are not considered as violations of the rules (if they allow to finish examination).
