In this study, it was aimed to determine the linear and curvilinear relationships between adolescent aggression and sociometric popularity. 524 adolescents randomly selected from 20 elementary schools in Nigde city center formed the study group. The participants were from 8th grade in 20 different classrooms. The research data were collected by applying Aggression Scale and doing Sociometric Measurement. Sociometric Measurement was done by asking the students to write the names of three of their friends from their classroom on preprepared forms that (i) "they most want to spend time with" (ii) "they least want to spend time with". Since the aggression and sociometric popularity scores showed differences based on gender, analyses were performed separately for girls and boys. Because there was not a meaningful relationship between girls' sociometric popularity scores and aggression (in five types) scores, regression analysis was not conducted with the data obtained from female adolescents. For boys, linear and quadratic regression analysis was carried out to explain the relationships between their sociometric popularity and aggression. The results showed that the least preferred and the most preferred boys' aggression (except anger) levels were high.
