The validation of the research objectives set was carried out by means of the static nonparametric method of
Pearson chi-square (Pearson's chi-squared test), which helped us to determine the level of the dependence of the
results on a particular feature, significant for a group of respondents, such as gender or age (Chráska 1998,
Greenwood, Nikulin 1996). To determine the significance of particular groups of respondents who answered the
same way, basic descriptive statistics and their visualization through tables was used. For the calculation purposes,
the statistical system Statistical 9.0 (Nisbet et al., 2009) was applied.
