For each variable, the lowest (*) and highest (ʃ) differences are indicated. Variables that are considered more desirable are noted as D, and variables where desirability does not come into play are noted nD (e.g., more hygienic actions and shorter waiting times are considered desirable). To be statistically significant a variable requires z < −1.96
