Factor analysis is a statistical method used to identify underlying structure of variables in a data set. There are several synonyms for factor analyze, including latent variable analysis, factor extraction, and principal component analysis. While each of these methods differs slightly in their approach and interpretation, they all share the common goal of identifying relationships and patterns in complex data sets, and reducing the dimensionality of the data. Factor analysis can be applied in a wide range of fields, from psychology to marketing to engineering, and can provide valuable insights into the factors that drive trends and behaviors across diverse populations.
