This course focuses on the importance of building models that match both data and theories when investigating variables that are not easily quantifiable. It helps you understand dimensionality and perform exploratory and confirmatory factor analyses, which are statistical techniques used to create and refine measures in fields such as economics, psychology, and education. The course also emphasizes the significance of sharing and distributing these measures. By learning how to conduct factor analysis using R, you will gain valuable skills in analyzing and interpreting complex data sets.
