Statistical Analysis on Satisfaction of Residents Living in Prefabricated Concrete Buildings in Thailand

Abstract:

Sample survey has been conducted to evaluate satisfaction of residents living in prefabricated concrete buildings (dormitories, detached houses, and townhouses) in Thailand. Nine criteria have been determined including moisture protection, noise prevention, safety of structures, thermal prevention, air flow, external appearance, interior, facility, and overall satisfaction. The t-test indicates that the satisfaction score mean between males and females for each criterion is not significantly different. The Levenes test shows that our survey data do not follow homogeneity of variance assumption for ANOVA F-test for most criteria, except for airflows and overall satisfaction criteria. Welch and Brown-Forsythe tests are then used under non-homogeneity of variances. The tests reveal that all criteria show a significant difference among habitats groups, but not for the thermal prevention criterion. Some multiple comparisons also show many pairs of significant mean difference among habitat groups.
