Generated results were evaluated to ensure that factors are assigned to an appropriate group. Evaluation involved relocation of factors to ensure that the factors are logically placed in their respective group. The evaluation resulted in 7 groups only where the groups were given names related to the nature of factors in them. Results from categorization can be used for advance analysis such as structural equation modelling which required groups as latent variables.
