In this instance, the researcher applied a graphical method for detecting the univariate outliers, and the Mahalanobis’ distance case was applied for determining the multivariate outliers in order to confirm their effect (Hair et al., 2010). Using Box Plot, 3 univariate outliers were established and marked with asterisks; these, once detached and compared with the Mahalanobis’s distance test, identified multivariate outliers (Hair et al., 2010). Having the graphical and test results, three outlier cases are thus confirmed. Moreover, after determining outliers in this study, adjustments have been made by removing three (3) cases, and thus the size of the sample (N) was reduced to 428 for the final study.
