5. Results and statistical analysis

Practical part

The figures 25-37 represent statistics summarizing information on practical part. The results of 4 practical tests were analyzed – Zoology, Botany, Molecular biology and Dendroecology.

Figures 25-34 show the participants density trace as well as the observed minimum, observed maximum and the possible maximum in practical tasks in appropriate biology sub-branches. The results of all practical tasks (Fig. 26, 28, 30, 32) as well as total density trace (Fig. 34) correspond to the general curve of distribution.

The students were divided in the morning and afternoon groups. So the results of the morning groups were compared with the results of afternoon groups (Fig. 35 - 36). There was no useful difference between the obtained results of students from these groups.
