We examined whether

path coefficients differ between individuals with cognitive disabilities and those with non-cognitive disabilities through multiple group analyses.

Table 5:

Path coefficients, t-statistics & coefficient of determination.

Final model with significant

path coefficients is given in Fig.

MacKinnon, Lockwood, Hoffman, West, and Sheets (2002) compared the various ways to test the statistical significance of the mediating effect in a Monte Carlo study, and recommended testing the joint significance of the two

path coefficients comprising the mediating effect.

PC) are equal to the

path coefficients that can explain the change of standard deviation in a dependent variable occurred by the change of standard deviation in an independent variable, when all other fitted independent variables were held constant.

Path coefficients, determination coefficients, and correlation index were calculated.

The value of

path coefficients are found out for the conceptual model developed and tested empirically for each company understudy.

The numbers above the arrows, in Figure 1, are referred to as standardized

path coefficients and are analogous to regression coefficients or standardized beta weights in multiple regression (Keith, 2006).

Generally, the hypotheses proposed in the research model are supported by the data with

path coefficients at highly significant levels and in the predicted directions.

All ofthe

path coefficients in the free and constrained models were highly significant (p < 0.

05 level of significance on the appropriate

path coefficients.

In their findings, significant

path coefficients existed between service quality and customer satisfaction, and between customer satisfaction and purchase intention.
