#### 3.2.3 In Depth Analysis of Clusters Obtained for Educational Videos  
Students who strongly agree with the benefits of educational videos are more than three-quarters females, evenly distributed by age group, and who enjoy using multimedia resources in the learning process. The main purpose for which Internet services are used is still communication, but a high percentage of students also uses these services for information, followed by entertainment and domestic facilities.

Table 5: Comparative study of clusters identified for the benefits of educational videos. a medium or low extent with the benefits of educational videos are mainly young, aged between 18 and 20. Almost half of them are neutral in terms of systematic use of multimedia resources in the learning process. Most of them use Internet services for communication, a third of them use such services for entertainment, a quarter use them for information, and only a few use them for domestic facilities.
