Course Syllabus


This course lasts for three years. The 1st year aims at beginners. This year starts from introductory topics (variable types, hypothesis testing, descriptive statistics) to working with some methods (chi-square, t-test, nonparametric statistics, one-way ANOVA, and linear regression). The course covers the building blocks of quantitative data analysis with the aim to train students to be informed producers and consumers of quantitative research. The applied part introduces working in R (RStudio) for calculations and reporting. No prior knowledge of R is required, but understanding the key ideas in statistics and probabilities is an asset. This course is the starting point for students interested in pursuing training in advanced methods of data analysis or planning to use quantitative methods in their own research.
Learning Objectives

Learning Objectives

  • develop skills necessary to solve typical data analysis problems on social data in the R software environment
Expected Learning Outcomes

Expected Learning Outcomes

  • Conduct statistical analyses in RStudio
  • Choose appropriate methods and techniques for certain types of variables and certain aims of the analysis
  • Give meaningful interpretation of statistical results: regression coefficients, tables, plots and diagrams (produced in R)
  • Perform data transformations
  • Represent graphically the results of the statistical analyses
  • Create analytical reports describing all the stages of analysis and interpreting its results

Assessment Elements

Assessment Elements

  • non-blocking Projects
    Late submissions are not considered (try us). If you are ill during the project submission, present a medical certificate to get the formula adjusted for you. If you miss more than one project, there might be a makeup assignment. When you submit a project in MS Teams, you must click on the "Turn in" button to complete the submission. All projects are, first, posted to the dedicated channel where they are peer-reviewed, and submitted in the Assignments section by each contributing student. If you have any questions about the project, sign up for a consultation.
  • non-blocking In-class activity
  • non-blocking Exam
