A srarisrically significanl difference was obtained in academic achievemem and aggression in favor of males r (284) =3. -13-1, p < 0.05 and r (28-1) =3.82, p < 0.05 respecrively Similarly. a slarisrically signijicanr difference was observed helween male and female selt: esteem scores in favor of' females (I (28-1) =--1.071.
