The review reports, citing Jackson et al. (2015), that in an average classroom of 20 children relational aggression nominations had "M = 3 peers, SD = 2.4 peers" and physical aggression M = 4 peers, SD = 3.8 peers, indicating some children are noticed by many classmates as less peaceful.
"relational aggression nominations ranged from no received nominations to 14 nominations (M = 3 peers, SD = 2.4 peers). Physical aggression even ranged from no nominations to nominations by all classmates (M = 4 peers, SD = 3.8 peers"
