Figure 5: Dendrogram of agglomerative clustering analysis
Figure 6 presents detail description of the five clusters created. Each cluster is represented by one
color in the boxplot chart. The most interesting results are at first four properties. Red cluster is typical
by average level at all properties except kinesthetic, auditive and verbal property. Yellow cluster is
described by very high values of auditive property. Green cluster is characterized by low value of
kinesthetic property, high value of auditive and verbal properties. Blue cluster is described by higher
value of kinesthetic, low value of auditive and above average value of verbal property. Black cluster is
typical by its high value of visual and auditive property and low value of kinesthetic, social and verbal
property. The main finding is that the clusters of students depend mainly on type of perception of
students.
