All of the common parametric methods (ât methodsâ) assume that in some way the data follow a normal distribution and also that the spread of the data (variance) is uniform either between groups or across the range being studied.
Factor analysis is related to principal component analysis (PCA), but the two are not identical. Latent variable models, including factor analysis, use regression modelling techniques to test hypotheses producing error terms, while PCA is a descriptive statistical technique.xploratory factor analysis (EFA) is used to identify complex interrelationships among items and group items that are part of unified concepts. The researcher makes no a priori assumptions about relationships among factors.
