Factor Analysis using Principal Component Method in SPSS
Factor analysis is a statistical method that can be used to reduce many variables into a smaller number of factors that explain the underlying structure of the data. Principal components analysis (PCA) is a type of factor analysis that is commonly used in practice. PCA works by transforming the original variables into a new set of variables called principal components.
