4.2.2 Univariable and Multivariable Analysis
After the normality test, the univariate outliner and Mahalanobis values were determined by the standardised Z-score to see the existence of
the multivariable outliner and the intense value of the 2 tests (outliner). The results of standardising z-score values show that no value exceeds
+4 to -4(no additional output because of size constraints). Therefore, these values do not have extreme values (Coakes & Steed, 2003). The
utmost Mahalanobis of the three variables utilised in this study must not exceed 16.266 (Hair et al., 2007; Tabachnik & Fidell, 2007).
Therefore, there is no outlier because the most value of Maanalobis is a smaller amount than 16.266 as in Table 4.2. Regardless of whether
it is univariate or multivariate, conclusions are drawn without taking extreme values, and the isometric hypothesis is satisfied.

4.3 Preliminary Testing: Compliance with Regression Assumptions

4.3.1 Multicollinearity Analysis
The hypothetical model uses colinear analysis to check tolerance and variance inflation factor (VIF) values. If the worth of tolerance is larger
than 0.2 (Grason,2012), where VIF is a smaller amount than 10 (Pallant,2015), significance is assumed. The subsequent results in Table 4.3
show that price, product quality, and repair quality contribute significantly to the variable quantity of customer satisfaction. So H1, H2, H3 are
accepted. H1, H2, and H3 are statistically obsessed with customer satisfaction.
