4.11 Confirmatory Factor Analysis (CFA)

4.11.1 Confirmatory Factor Analysis Basics

Since the measurement model aims to improve the model before the estimation of the hypothesized model, the standardized regression weights for the research indicators were first examined by

conducting the confirmatory factor analysis (CFA) for each variable. Using factor loading technique, seven of the items was deleted. Items that have loaded more than 0.50 on their underlying construct are kept and items which have loaded less than 0.5 have been deleted. In general, the attained loads are satisfactory and acceptable (Byrne, 2010 and Hair et al., 2010). Therefore, all the indicators in the present study are related to their particular constructs and there is a satisfactory proof of the convergence validity of the model.

A key factor to consider when implementing Structural Equation Modelling is to determine to what extent does a hypothesized data “fit”, or in other words, if the hypothesized data adequately and satisfactory describes the sample data. Ideally, the evaluation of a model fit should be considered from a variety of perspectives, where the evaluation shall consider various criteria that assess model fit. An R Square = 0.319 was attained. Moreover, it was concluded that the seven service quality dimensions suggested in this study are devoted to around 32% of the variation in the dependent variable (Satisfaction). The fitness is in general acceptable and satisfactory. This is supported by the values of the CFI and TLI indices.

4.11.2 CFA for Satisfaction

This scale consists of three items, where none of the items were removed as the standardized regression weight for all indicators is higher than 0.5. Considering the analysis results attained, the factor loadings of the observed variables ranged from 0.82 to 0.86 and were statistically significant. This provides a clear evidence of validity.

In addition, the lowest factor loading was for: Satisfaction_1: I have truly enjoyed attending this university, where the highest factor loading was for: Satisfaction _2: I am satisfied with my decision to attend this university.

4.11.3 CFA for University Image and Reputation

This scale consists of eight items, of which two were removed based on the reliability analysis results. Of the six remaining items, two items were removed due to low factor load, below 0.5. The two removed items are:

• image_reputation_P_6: The tuition I pay is worth the quality of services I am receiving from my university.

• image_reputation_P_4: This University has been recommended to me by alumni or a friend or family.

4.11.5 CFA for Quality of Education

This scale comprises three items, and none were removed as the standardized regression weight for all indicators was found to be higher than 0.5. The results for the factor loadings of the observed variables ranged from 0.68 to 0.77 and were statistically significant. This shows a clear evidence of validity.

95 4.11.6 CFA for Campus Physical Facilities

This scale consists of fifteen items. Of the fifteen items, five items were removed due to the reported low factor load which is below 0.5. The five items are:

• facilities_P_7: My University offers comfortable accommodation (dorms).

• facilities_P_8: My University offers accommodation (dorms) at an affordable price. • facilities_P_9: My university accommodation (dorms) is safe.

• facilities_P_14: My University offers parking areas for students. • facilities_P_15: I feel safe anywhere on campus.
