The thirds hypothesis was tested using one way ANOVA analysis showed that group thinking has an influence on criminal behaviour among adolescents, F(299) = 5.768, p<0.05, group cohesiveness does not have a significant influence on criminal behaviour of adolescents, F(299) = 2.124, p>0.05. the results were discussed in line with relevant empirical literature, conclusion and recommendation.
