4.1 PRELIMINARY TESTING: COMPLIANCE WITH REGRESSION ASSUMPTIONS
This research conducted a preliminary test to satisfy the multiple regression analysis’s assumptions. The assumptions were the
normal data: there were no extreme values (outliners) and no multicollinearity issues.
4.1.1 NORMALITY TEST
George & Mallery (2010) mentioned that the results for skewness and kurtosis must not be more than 2 and not smaller
than -2. Table 4.3 shows the skewness and kurtosis results for four variables and customer satisfaction. All variables
were found to have acceptable ranges of 2 and -2. Thus, this study gained the normal distribution data.

4.1.2 UNIVARIABLE AND MULTIVARIABLE ANALYSIS
2
Existence of extreme value (outliners) conducted after normality test. Standardised z score and Mahalanobis D Test
were conducted to determine univariate outliers and correspondingly defined the presence of multivariate outliers.
