1. Factor Analysis Factor analysis is a statistical procedure utilized for data reduction (Bartholomew et al., 2008). This reduction is reflected in lowering a large number of variables that have similar characteristics, into smaller factors (dimensions). Specifically, based on data reduction, factor analysis is conducted to identify the unobservable and underlying structure of a set of variables which are correlated with each other.
