Moreover, the present study was to find out the differences in emotional intelligence and aggression of students among demographic characteristics (gender, grade and school types). The quantitative research design and descriptive survey method were used in this study. A total 1054 students from selected Basic Education High Schools in Yinmarbin Township were selected as participants by using simple random sampling technique. As research instruments, Emotional Intelligence Questionnaires (Bar-On’s Emotional Quotient Inventory: Youth Version (Bar-On EQ-i: YU) (Bar-On & Parker, 2000) and Aggression Questionnaires by (Nor Hasliza bt Faris, Noor Azniza bt Ishak, Fatimah Aailly bt Ahmad Ramli, 2016) were used to measure adolescents’ emotional intelligence and aggression. After that, the data were analyzed by using descriptive statistics and t Test. The results revealed that it was found no significant difference in emotional intelligence by gender but there was significant difference in aggression by gender in which male students were significantly higher in aggression than female students. Furthermore, there were significant differences in both emotional intelligence and aggression between Grade 10 and Grade 11 students. Grade 11 students were higher in emotional intelligence than Grade 10 students and Grade 10 students were higher in aggression than Grade 11 students. And then, significant differences were found in emotional intelligence and aggression by school types. Private school students were higher in emotional intelligence than government school students and government school students were higher in aggression than private school students. Moreover, Pearson Product Moment Correlation revealed that emotional intelligence of adolescents was negatively correlated with their aggression (r = -.320, p<0.01). Therefore, if the students had higher in emotional intelligence, their aggression would be less.
