In multivariate statistics, exploratory factor analysis (EFA) is a statistical method used to uncover the underlying structure of a relatively large set of variables.

There are two approaches to factor extraction which stems from different approaches to variance partitioning: a) principal components analysis and b) common factor analysis.

Dec 18, 2025 · Factor analysis is a method that aims to uncover structure in large variable sets. If you have a data set with many variables, some of them may be interrelated, i.e., correlate with each …

Mar 13, 2025 · Exploratory Factor Analysis (EFA) is a statistical technique used to identify underlying factors or latent variables that explain the pattern of correlations within a set of observed data.

Exploratory factor analysis is a statistical technique that is used to reduce data to a smaller set of summary variables and to explore the underlying theoretical structure of the phenomena.

In Exploratory Factor Analysis (EFA), we are essentially exploring the correlations between observed variables to uncover any interesting, important underlying (latent) factors that are identified when …
