Table 4.
Mann–Whitney test parameters for selected questionnaire items. Example of the item coding system: QXX_ETR = Q (question) × X (item order in the questionnaire), _ETR (item-related driver). For the Mann–Whitney test, the location parameter is given by the Hodges–Lehmann estimate. Levene’s test is significant (p < 0.05), suggesting a violation of the equal variance assumption (it may determine a bias in the interpretation).
