## 3 Results
This analysis is extremely useful, as it highlights the differences of opinion between the age groups for each trait measured at the level of each item. It is noticed that the average values are close for the group of those under 20 years and those aged 20-30 years, in this case the differences being small and statistically insignificant for all 23 items in the table. \begin{table}
