The statistical methodology used to solve the raised hypotheses will be the causal analysis since it allows to analyze relations of causality between constructs that are not measurables of a direct way, but which they are pronounced through certain observable characteristics. The type of causal analysis used will be the model of structure of covariance also called structural equations model (SEM) and it will be solved with AMOS 16.0.
SEM methodology has been already used by different authors to measure the effects of Co-creation [15] and [30], SEM methodology has been also used to measure empirically the influences between variables in the education sector [29] and [33].
In the structural equation model of this study, we examined the two level of analysis—the measurement model and the structure model.
