We calculated Cronbach‟s alpha scores for each independent variable to test the reliability of all scales which was between 0.700 and 0.941. All reliability statistics were over
0.7 (table 1),which confirmed that items for each construct variable in SAT model have
good reliability.
We used exploratory factor analysis utilizing principle component method for factor extraction and varimax rotation technique to examine the validity of each independent variable. Measurement items which has factor loading less than 0.5 were cut off. After running SPSS,we found no any itmes to be cut off ,in turn,new construct variable happened named “facility” that loaded 2 items ;PHY5 and PHY1, which spiltted from “physical quality”. Therfore, we renamed the old “physical quality” to “room quality” which loaded 3 items ;PHY2,PHY3,PHY4 (Table 1).
