2. Considering the factor of non-response in sample size (n1) Since the basic research – results of a similar study did not exist before, non-response level was assessed expertly and it was 20%. Primary sample size was corrected according to the respective indicator. Results are given in the form of table: Consideration of the factor of non-response in n1 (20%-factor of N sample size by directions is considered) Agricultural sciences 174 217 Business Administration 231 289 Art 222 277 Health 185 232 Engineering other 233 292 – Engineering IT 213 266 – Engineering-Building 190 238 United Science 152 190 Interdisciplinary Tourism 234 292 – Engineering transport and interdisciplinary – 213 267 marine sciences Total 2047 2559 3. Compiling the groups to be interviewed since the number of students to be interviewed – is defined, including 20% of non-response, we have to identify how many groups are required in each direction. For this n1 was divided into the average number of students by directions. Results are presented in form of table: Average n2 identification of primary number of groups by number of n1 (number of directions students in groups) the group 10.5 217 21 Agricultural sciences 16.7 289 17 Business Administration Art 13.1 277 21 Health 15.5 232 15 Engineering other 11.6 292 25 – Engineering IT 15.1 266 18 – Engineering-Building 10.6 238 22 United Science 17.6 190 11
