Abstract

Advanced Data Analysis in Sociology focuses on categorical data analysis and covers special types of prediction and classification models (logistic regression and cluster analysis). The course continues with a discussion of data culture, from data management to narrating with data. This course is also the starting point for students interested in pursuing advanced training in research methods or planning to use quantitative methods with categorical outcomes in their own research.
Learning Objectives

Learning Objectives

  • The course covers the foundations and popular techniques of categorical data analysis with the goal of training students to be informed producers and consumers of quantitative research.
Expected Learning Outcomes

Expected Learning Outcomes

  • Students can apply classification techniques, propose hypotheses and choose the methods in categorical data analysis in R, including supervised classification with a binary outcome, and unsupervised classification with clustering techniques of mixed data types.
  • Students interpret the results and assess the quality of proposed analytical and visualization solutions, provide reasons for their choice of techniques, interpret the outputs correctly, and assess the quality of models and data stories.
