Within the framework of the theory of latent variables, the latent variable “physical aggression of teenagers” is measured on a linear scale. It is shown that the used set of indicators (questionnaire points) allows measuring both low, and high level of teenagers’ physical aggression. The analysis of teenagers’ physical aggression depending on grade and gender of teenagers is carried out. The analysis of variance has shown that on the average young men are more aggressive, than girls are. However, there is no statistically significant difference on an investigated latent variable between classes.
