SPSS 11.5 were then used to test the validity and reliability of those two measurement methods. Spearman rank correlation technique dan were used to analyze data taken from 129 students of Grade II SMU YKM Tanjungsari. Statistical analysis conducted in this research was given the result of -0,673 whilst by using testing criterion with significany 5 percent would then concluded that the research hypothese is acceptable. Brief conclusion from this research was given a result that there is a negative relations between conformity toward the peer group with indisciplinary behavior conducted by Grade II students at SMU YKM Tanjungsari.
