Factor Analysis

A statistical method for investigating relationships between variables that are not easily measured directly. Most commonly works by assigning similar variables into groups called dimensions. Factor analysis is a ‘dimensionality reduction’ technique. That is, it seeks to explain patterns in a  large number of variables by identifying a smaller number of underlying latent variables (‘factors’).

Summary (bullet points)

Can be explanatory or confirmatory

  • Explanatory factor analysis aims to find hidden relationships between variables when you have no idea what they might be
  • Confirmatory factor analysis relies on the researcher having an idea about how the relationships might be structured and seeks to confirm these ideas
